EXIF data (outdated)
For Exif data you need to have PHP compiled with --enable-exif flag. pixelpost admin panel will report if you have an exif-enabled install or not. If you do, pixelpost will automatically try to retrieve data from images. Exif support is not very tested, it works on my install with my camera and my images.
It might be shaky.
If anyone know of another way to retrieve exif-information without relying on php being compiled with enable-exif, please tell me. It don't appear to be the most common thing.
Also, bare in mind that the most widely used image-editing software, the almighty Adobe Photoshop, kills all exif data in any file touched by the application.
Guest helped me on this one, together with GreenTraveler:
You can preserve EXIF data in photoshop if you just do a save or save as instead of "Save for Web". Of course this only works if you've edited your image without using layers. The latest version of Photoshop (CS) supposedly saves EXIF data..
Thanks for the info there.
