hey aussie a possibility that might help you with proof, is that your camera might have recorded the settings it used to take the pictures, into the file. Using my picture editors "finepix viewer" and "photoimpact pro" i was able to see the camera settings of my pictures. The settings in finepix actually list my camera type, and date etc. of each picture. I tried to find a way to do it in adobe photoshop but I only have the starter edition and don't know if the starter doesnt have this ability or if I just couldn't find it.
I attempted to view the settings of one of your pictures on the first page and they weren't on the file, maybe those settings are somehow removed in the process of uploading them onto the web.
