1. Purpose and Scope
The purpose of this Image Manipulation Policy is to establish clear standards for the preparation, processing, presentation, and assessment of images and image-based data submitted to the journal. The policy aims to preserve the integrity, accuracy, and transparency of visual materials that form part of the scholarly record.
Images—including photographs, micrographs, gels, blots, radiological images, charts, and other visual representations of data—play a critical role in the communication of scientific findings. Inappropriate image manipulation, whether intentional or unintentional, can misrepresent results, compromise reproducibility, and undermine trust in published research.
This policy seeks to ensure that:
- images accurately represent the original data and observations;
- any image processing is applied in a transparent, consistent, and scientifically justified manner;
- visual data are not altered in ways that mislead readers or distort interpretation;
- responsibilities and expectations related to image integrity are clearly defined.
1.1 Scope of the Policy
This policy applies to all image-based materials associated with manuscripts submitted to the journal, including but not limited to:
- figures and figure panels;
- supplementary images and visual data;
- image-based datasets;
- graphical representations derived from experimental or observational data.
The policy applies to all participants in the publication process, including:
- authors preparing and submitting manuscripts;
- peer reviewers evaluating image-based content;
- editors and editorial staff responsible for assessment and decision-making.

1.3 General Applicability
This policy applies to all submissions, regardless of discipline, image type, or technical complexity. It covers image handling at all stages of the publication process, including:
- manuscript preparation;
- peer review and editorial assessment;
- post-publication review and correction.
The journal recognizes that image processing practices may vary across disciplines. Accordingly, this policy is intended to provide a principled and adaptable framework while maintaining a consistent baseline standard for image integrity.
2. Definition of Image-Based Data
For the purposes of this policy, image-based data refer to any visual material that represents, records, or derives from empirical observations, measurements, or analyses and that contributes directly to the scientific evidence, interpretation, or conclusions of a manuscript.
Image-based data include both original images and images that have undergone permissible processing, provided that such processing does not alter the scientific meaning of the data.
2.1 Types of Image-Based Data
Image-based data may include, but are not limited to:
- photographs of experimental setups, specimens, or materials;
- microscopy images (e.g., light, electron, confocal, or fluorescence microscopy);
- gels, blots, and electrophoretic images;
- radiological or medical images;
- remote sensing or imaging-based observational data;
- images generated through computational modeling or simulation, where such images represent analytical outputs;
- figures, graphs, and visualizations derived directly from primary data.
2.2 Original Images and Source Data
Original images refer to the primary, unprocessed visual data captured during the research process. These may include raw image files, original scans, or instrument-generated outputs prior to any processing, adjustment, or enhancement.
Authors are expected to retain original images and associated metadata to allow verification of image integrity where necessary.
2.3 Processed Images
Processed images are images that have undergone adjustments or transformations, such as cropping, contrast adjustment, color balance correction, or noise reduction, applied for clarity or presentation purposes.
Such processing is permitted only when:
- applied uniformly and consistently;
- scientifically justified;
- transparently documented;
- not misleading or deceptive.
2.4 Composite Images and Figure Assembly
Composite images refer to figures composed of multiple images, panels, or visual elements assembled into a single figure.
Composite figures must:
- clearly delineate individual components;
- avoid duplication or selective reuse of image elements;
- accurately reflect the relationship between the combined elements.
2.5 AI-Generated or AI-Modified Images
Images generated or modified using artificial intelligence or automated tools are considered image-based data and are subject to the same standards of integrity, transparency, and disclosure as other image-based materials.
The use of AI tools in image generation or processing is further governed by the journal’s AI and Generative Tools Policy.
2.6 Illustrative and Schematic Images
Illustrative or schematic images created solely for explanatory or conceptual purposes, and not representing empirical data, must be clearly identified as such.
Such images must not be presented in a way that could be confused with image-based data or experimental results.
3. Principles of Image Integrity
The integrity of image-based data is essential to the reliability, reproducibility, and credibility of published research. Images must accurately represent the original observations and data on which scientific conclusions are based.
The following principles govern the preparation, processing, and presentation of all image-based materials submitted to the journal.
3.1 Accuracy and Faithful Representation
Images must faithfully represent the original data without alteration, enhancement, or omission that could mislead readers or distort scientific interpretation.
Any processing applied to images must preserve the underlying scientific information and must not introduce features, remove relevant elements, or alter the relative relationships within the image.
3.2 Transparency of Image Processing
All image processing must be transparent and scientifically justified. Authors must be able to explain:
- what processing was applied;
- why such processing was necessary;
- how processing was performed.
Undocumented or undisclosed image manipulation is not acceptable.
3.3 Consistency and Uniform Application
Image adjustments must be applied consistently across the entire image and, where applicable, across comparable images within a figure or dataset.
Selective adjustment of specific regions, features, or data points within an image is not permitted unless explicitly justified, clearly described, and scientifically appropriate.
3.4 Preservation of Original Data
Original image data must be preserved and retained by the authors to allow verification, replication, or editorial assessment.
Authors must not discard or overwrite original image files in a manner that prevents verification of image integrity.
3.5 Distinction Between Data and Illustration
Images that represent empirical data must be clearly distinguishable from illustrative, schematic, or conceptual images.
Illustrative images must not be used in place of data or presented in a way that implies experimental evidence.
3.6 Proportionality and Minimal Intervention
Image processing should be limited to the minimum necessary to enhance clarity or visibility without affecting interpretation.
Excessive or unnecessary manipulation, even if technically possible, is inconsistent with responsible scientific practice.
3.7 Accountability and Responsibility
Authors bear full responsibility for the integrity of all image-based data included in their manuscripts. This responsibility extends to images prepared by collaborators, technicians, or third parties.
Claims that image manipulation resulted from software defaults, automated tools, or technical error do not absolve authors of responsibility.
4. Acceptable Image Adjustments

- can be addressed without altering the overall conclusions of the work;
- involve presentation or labeling issues that require clarification.
Corrected images or revised figure legends must accurately reflect the original data.
16.4 Expressions of Concern
An expression of concern may be issued where:
- serious questions exist regarding image integrity;
- available information is insufficient to reach a definitive conclusion;
- investigations are ongoing.
Expressions of concern are intended to alert readers while further assessment is conducted.
16.5 Retractions
A retraction may be issued where:
- image manipulation substantially undermines the reliability of the data or conclusions;
- fabricated, falsified, or misleading images are identified;
- image-related issues constitute research misconduct.
Retractions are intended to correct the scholarly record and do not necessarily imply intent or misconduct by the authors.
16.6 Transparency of Post-Publication Actions
All post-publication actions related to image manipulation are clearly identified, publicly accessible, and permanently linked to the original article.
Notices describe the nature of the issue and the reason for the action, while respecting confidentiality and due process.
16.7 Author Cooperation
Authors are expected to cooperate fully with post-publication assessments and corrective actions.
Failure to cooperate may influence the outcome of post-publication actions.
17. Appeals and Author Responses
The journal recognizes the importance of a fair and transparent process when handling image-related concerns. Authors are provided with an opportunity to respond to editorial findings and, where appropriate, to appeal decisions related to image manipulation.
17.1 Author Responses
Authors are entitled to respond to image-related concerns raised during editorial assessment or post-publication review. Responses should:
- address the specific issues identified;
- provide relevant evidence or documentation, where requested;
- be submitted in a timely and professional manner.
Responses that do not address the substance of the concern may not be considered sufficient.
17.2 Appeals of Editorial Decisions
Authors may appeal editorial decisions related to image manipulation where they believe that:
- the decision was based on a factual error;
- relevant evidence was not adequately considered;
- a procedural issue affected the outcome.
Appeals must be supported by a clear and reasoned explanation and must address specific points raised by the editorial team.
17.3 Scope and Limits of Appeals
Appeals based solely on disagreement with editorial judgment or on general objections to journal policy are not normally considered.
The journal does not reopen cases where appeals do not present new or substantive information.
17.4 Appeal Review Process
Appeals are reviewed by a senior editor or member of the editorial team who was not directly involved in the original decision, where possible.
Following review, the editorial decision may be upheld or, in exceptional cases, reconsidered.
Decisions made after the appeal process are final.
17.5 Confidentiality and Professional Conduct
Appeals and author responses are handled confidentially. Authors are expected to engage respectfully and professionally throughout the process.
Abusive, threatening, or inappropriate communications may result in the termination of the appeal process.
