Background image not loading.

I have a screenshot of a sat map (jpeg 640x480) i had loaded to my dude server. It’s less than 100k big, but when i try to load the network map that uses it as a background it just hangs on “loading…”

I am using 4.0 b3, I have another background working on another network map using a jpeg but its only 35k big. Am i missing something obvious? is this a bug?

Ah this is a bug. The search feature served me well…
