Stick with IPTC. You won't be sending your original files to average Netizens anyway. Every good html gallery program or online photo gallery can read the IPTC fields like author and caption and automatically add them to the gallery in html format. And if you catalogue your images, IPTC fields are great for it. Also, I believe the WinXP "properties" of the file are not transferred with the file. They are most likely stored in the NTFS filesystem on your disk (that might explain why you can't change them, if you don't have the files on a NTFS partition). Anyway, IPTC is non-proprietary while the WinXP properties are very proprietary and not supported anywhere else, even if they transfer with the file to other filesystems. Good light! fra
