Misbehaving Blogger

I'm way behind in posting about recent trips and such but Blogger insists on turning my pictures on their sides and I can't figure out how to make it stop or how to rotate them upright so I keep getting pissed off and quitting.  So, if anyone knows how to make Blogger behave please let me know!  Otherwise, you'll have to keep turning your head or your computer screen in order to view the pictures.  And since I hate having to do that I don't want to make you do it either.
