resizing photos

If you want to find out the real size of a file, open it in MS Paint, which will never resize your photos. What you see is what it is. (And if you make it smaller, and save it, that's a permanent change--you can never stretch it bigger again without making the image blurry.)

Oh my God--was that was that the explanation?! I couldn't even make my brain do that!
