I could walk you through the process you want, but that's be like helping you build a paper airplane when you just as easily build a jet instead. :smileywink:
You should store your pictures (or references to them) in a separate table and relate it to your membership database. Then you simply add new records to your picture table each time you revise a picture. The relationship can be designed to automatically display the most recent photo, but the original photos would still be available in the Database file for archival purposes.
Will that work for you?
