I need to figure out the sideways picture BS, they're upright in my computer..............
If taken with a camera or cellphone in 'portrait' perspective, part of the file says to rotate 90 degrees. When you upload to magazine that rottate part gets lost. On my cellphone, I CROP the photo and save it.. On a computer, try 'save as' something simple like bmp, then do your upload. (You might have to convert it to a jpg first - I've never tried that.)
