It is fairly easy to do a screen shot (print screen) of the photo while viewing your PC display, then open Microsoft “Paint” and “Paste” the photo into the working space. Paint has a “crop” command where you can select the important parts of the photo. Then click on “file” and “Save As”. Once you get to that point, your selections include shrunk down email files, JPEG files, etc. some much less megabytes than the original. Paint is included free on Windows 7 and before, most computers have it installed already. This takes longer to describe than to do, and it is how I get custom thumbnail photos for YouTube videos. I’m sure there are even better ways like Dave suggested.
