I use Irfanview for ad hoc resizing, etc - it preserves the metadata.
On the coding side, I use a DLL version of MediaInfo <http://mediainfo.sourceforge.net/en> (the GUI is also useful - it installs as a shell extension) which gives more than enough info for images and videos, sound files, etc. There are code examples of usage, on the website. _____ Ian Thomas Victoria Park, Western Australia _____ OOOH! I just thought of something awful non-coding related ... What image editing apps preserve the properties when you alter an image. I often use the ancient ImageComposer 1.5 (anyone remember that?) and I know it loses the properties on save. I just ran an experiment with PaintShop Pro 7 and it also loses the properties. For each test I loaded a large Canon camera photo, resized it down and saved. Greg
