You have to use a "Hex Editor" which essentially shows you the code that makes up the picture, you can open anything with them. Can't remember
where I got mine, but there are numerous free ones around. Just open the picture with it and there's quite a bit of embedded information. On that one
I can see the camera make/model and date it was taken, but that's about it (I don't know about the various codes of other things, so I'm restricted
to the obvious

) Don't know how you can tell the resolution about it. Generally if it's been edited with a program it'll have "Adobe photoshop"
near the top (sometimes others, but it pretty much always mentions adobe). That's about all I know
If someone would like to contribute on some more clever techniques I'd be most abliged!
