Very cool photos and descriptions. Thanks for sharing.
To correct the orientation of the photos, you'll have to edit and overwrite them with a program like GIMP. This is like Photoshop but 100% free to use. As soon as you open the images, GIMP should ask you if you want to correct the orientation.
PS: I've found your post because @viking-ventures featured you in her entry for the Pay It Forward Contest
Thanks for visiting and for the advice. I'll download GIMP and give it a go!
I actually also recommend Photoscape - it's also free. I prefer to use it for all my photo needs.
