Keep a source-image reference for every figure panel

Give every panel a label and record the exact source file used. Include the source location or an internal identifier that an authorised colleague can resolve. A short filename on its own may refer to several files in different folders.

Record the crop and any processing applied to the displayed copy. Follow the requirements of the relevant journal, institution or project for what processing is allowed and how it must be reported. A panel list documents the assembly; it does not make an alteration acceptable.

Update the labels and panel list when you reorder a figure. Check the final exported figure against that list. A correct working slide can still be paired with an older export during submission.

Keep the source files and working records under the access controls appropriate to the project. For public examples, use permitted material and remove private identifiers from the example copy. The panel list supports figure organisation; it cannot establish the validity of experimental results.
