EXIF data contains the type of camera/scanner used, resolution, exposure time, and relevant tech info that most people don't pay much attention to with the "smart" imaging technology. It is info that is mostly relevant to professional and amateurs using digital imaging and is used for forensic purposes to detect forgeries using imaging software.
If you scan a document to your computer, send it to paint, which is NOT digital imaging software, then save it as a JPG or GIF, the exif data is NOT part of the resultant saved document. Likewise, if you edit, or change it, compress it, the exif data for that specific original is no longer elevant since the data has completely changed.

Examples below:

Thank you for that information. Unfortunately for me, I’m still just stupid enough that it sounds like German to me! LOL But I surely DO appreciate your information and I’ll continue reading it and maybe some small tidbit will sink in!

The samples in my last post ALSO explain the discrepancy between an image directly uploaded via camera phone and the image posted from Photobucket which was first scanned, sent to paint, and then uploaded from her PC to Photobucket as a JPG or whatever...

It takes a few minutes to pull Danae’s posts up from years ago, which I did when this first started. There is no earthly reason to believe that this person, who I don’t know and have had NO contact with, would suddenly revert to some insidious plotter to discredit anyone.
Danae, for whatever it’s worth, you have nothing to prove here.

WOW! I had no idea that so much information was in a digital picture! Thanks!
