Here's a more interesting question for you...
For each image, you'll have a form. Do you want:
- Submit button for each image
- Submit button for the entire page
If you go do #1, user edits 1 image and then must submit it. This can be a pain if the user wishes to modify 5 images. They'd have to update 1 image then submit. Update the 2nd image then submit. Rinse and repeat.
Option #2 is kind of nice. User makes the changes they need and click once to save them. Trick is you'll need to really keep track of the field names. I suspect this may be the most difficult part. But if you do a little planning, it can make it a little easier for your form processing code. But you'll need to do what's comfortable for you. Arrays will definitely be your friend for this type of stuff...
