I've never joined a blog before. Hope to ease my worries about posting by trying out the test bed first.
Make sure your photo is the right way up on your computer before you post it. If you're on a PC, a program like Windows Picture and Fax Viewer will show you which way is currently up and will allow you to rotate it so it will appear up in other programs. I think the problem is viewing photos using your camera software, which displays the photo orientation corrected when it won't really be in another program. I see now that I should add something about this to the How-to writeup on uploading photos.
