I know Bob S has mentioned this before, but why do my photos keep getting posted sideways????? Is there a fix for the site? Or a way to recognize this in my pics BEFORE posting them, even though they appear correct in my file?

It is the camera angle. Your camera rotates the photo as needed, as does your computer - they automatically interpret and display photos as normnal. Web pages won't though.

One thing you can do is take the image in Microsoft Photo Editor: Open in MS Photo, EDIT, Rotate, save as a copy.
