This is my first post on the forum but I have been using MP3Tag for quite some time and love it's features such as Filename/Filename renaming and so on.
It's such features that led me to post this suggestion. I was going through my old family photo library, adding tags here renaming files there. I usually do multiple file renames with some free web tool but I had recently used MP3Tag to rename some music files and wondered if I could use it the same way. I found that you could not but, being a programmer, thought it may be not too difficult add this feature?
Further, it would be great to have all the features of MP3Tag but specifically for picture tag editing - maybe a new application?
Hope this gives you some food for thought.
