Rotating Images

I am experiencing some problems with uploading images which then seem to rotate and sit on their side! Is there some way to manipulate and rotate images so they face the way you want them to?

This tends to be an issue if the image you uploaded was rotated using the context menu in Windows Explorer--that usually doesn't rotate the actual image. Your best bet is to rotate the images in an image editor (or with a local installation of image magic) prior to upload. Alternatively, I'm guessing it would be possible to add a rotate function to admin/files/show with a plugin.
