EXIF/IPTC Data on Resized Images
Erik Barzeski notes that Flickr only includes EXIF/IPTC information on your original images, not on the thumbnails and smaller versions. Amazingly, the Flickr staff seems to see this as a feature. I prefer to keep photos on my own servers, but none of the PHP-based gallery software that I’ve seen supports metadata on resized images, either. I wonder how easy it would be to add this using getimagesize and iptcembed. The ATPM galleries do include this metadata because the images were resized on my Mac using sips.
A bit late, but FWIW gallery2 (http://www.gallery2.org/) does seem to retain EXIF info for resized images.
