Best Practices for image data management include that at a minimum,  authors should:

  1. retain the original captured image and provided it if questions arise during review or after publication
  2. retain detailed records of the steps necessary to replicate the published image.

P.I. Outcomes has provided the following tutorial on metadata creation with Audit Trails for:

Adobe Photoshop,  ImagePro, and ImageJ

in order to automatically record replicable steps for digital image manipulation.    We continue to produce training materials and tutorials for this subject and welcome comments, corrections and suggestions.
