This could just be user error, but when I tried to post pictures directly to here using the controls on the "new post" page (click "additional options" at the bottom,) I kept violating the image size limit (300KB), which most modern digital cameras will do. You would have to modify the resolution and shrink the picture or host it somewhere else. There is also a 6 picture limit when using the built in controls. If I am doing it wrong, anyone else can step in and set him straight.
I definitely want to see your Africa pictures too, so I hope this doesn't discourage you!
