While were testing, I want to see what happens when I upload a picture without reducing the size of it first to the recommended 800 pixel width.
This picture is 1596 pixels X 994 pixels.

This picture is 3109 pixels X 1289 pixels, 2.86MB. and I left it showing as a thumbnail.
When I tried to load a picture a little larger than this I got an "ERROR" and it wouldn't load.
When all is said and done with I think using the 800 pixel size that is recommended is probably the best idea. It will upload much faster and show up on peoples screens faster too.
