EXIF data getting stripped on upload?

Blue Dragonfly

I have filled in the EXIF Artist and Copyright fields, as well as the IPTC Copyright Notice and Photographer fields, for new images I upload to my ZenPhoto gallery. The original image in the Albums folder has this information in it. However, the cached files are missing this information. Is this expected behavior? I'd expect the EXIF/ITPC data to be preserved, as ZenPhoto features the ability to display this information.

I'm not sure where to start digging for the source of the problem - PHP version (5.2.6), a plugin problem (GD2), or something in ZenPhoto? Hopefully someone can point me in the right direction! Thanks.

This is actually no problem. The GDlib (we have nothing to do with) does simply not support EXIF data as well as color profiles. The data is left intact on the full imges and should be fetched from there and be placed in the database when caching the images. There is also a button "refresh meta data" in some places.

This is a problem for me because I cache the full images to permanantly add the watermark, so the "originals" are never sent. I'd prefer the EXIF/ITPC data to remain there so if users copy the full image and post elsewhere, it will be easier to prove the images were originally mine.

I suppose the best solution, then, is to use my own software to add the copyright, and not use ZenPhoto to perform that step, thus serving the "real" full image. Am I thinking along the right lines?

Thanks for the fast response!

if you upload the files in the size you want displayed they do not get cached but are served directly from the original. Your other option is to watermark these images with your copyright.
