Just in case you didn't know, you can crop and rotate even after you upload!
Just go to the images page and click "crop and rotate" under the image. When the new window loads tick off the box that says "Enable clipping, apply to crop".
Two little handles will appear, top-left and bottom-right. Drag those in to where you want them and click "save picture".
Done! (You may have to refresh the page to see the new image.
Dsking, you can see I did one of yours....
