Resizing an image

When resizing an image dynamically and saving the new one on the server, is it possible, similar to the way touch() sets access and modification times of the file, to fill in the file “Comments” EXIF field?

Please advise, thanks.

Alright, StarLion, thanks for the comment. Could you recommend a library that would be able to handle the task I’m after?

Possible? Yes.
Native? No.

There are a few classes and libraries out there that will adjust EXIF information, but the PHP standard library only provides read functions.
