Scott's JPEG Commenter is an easy to use tool and helps inserting comments into JPEG files. It's meant to be fast, simple, and intuitive. The utility is free for noncommercial use. So why are JPEG comments useful? Well, they're kind of like writing on the back cover of a photograph -- you can jot down information about the image: where it was taken, who is in it, dates/times, etc. Scott's JPEG Commenter is additionally useful to view existing JPEG comments. Many programs (such as photoshop) automatically insert a comment. You might also find comments in photos that you download from the web. Scott's JPEG commenter can also be used to remove comments from images if you have a commented image that you want to de-comment.
