David Riecks’ site, Controlled Vocabulary, has drawn our attenion to photographer and web designer Laura Cotterman, who has discovered that resizing images on your website using the popular server-side application GD can inadvertently remove metadata from your image files. Many PHP scripts resize (or watermark) images with GD. Cotterman wrote the code for a couple of simple functions that can be added to PHP scripts for applications that use GD for image resizing so that the IPTC metadata is maintained. The functions are available at no cost under the GNU license and can be downloaded from her ImageMeta website.
