Here you go.
I use an open-source program called imagemagick to do all sorts of manipulations to pictures, including rotation and re-sizing for posting. It runs as a command-line program under Linux; probably also available under Windows/Mac. (Yes, in addition to being a cheese geek, I'm a computer geek!) For a GUI program, gimp is the cats meow for open-source programs, but it takes a few more steps to accomplish these sorts of tasks. In case you want the command I used to rotate and resize your pictures, here it is: convert image.jpg -strip -resize 1024x768 -quality 60 -rotate 90 press1.jpg
