OK now I see the little blue "Preview" in the upper right corner of the Compose window.
Now we can try a 640 by 480 size picture.
This was taken November 14, on a foggy ride through the Peaked Hill Land Bank property. I believe the rock in the distance (my mountain bike leaning up against it will give you an idea of it's size) is called Moshup's pillow.

It is funny how the picture isn't any larger. I like to look at larger pictures.
