Problem with some images on my LS, can anyone help?

This is what I'm going for.

This is what I've got.


The LS is called Frost.
I was able to switch the city/state for the weather perfectly fine and it's reading the correct temperatures. The problem, obviously, is that I can't get the weather icons to show. I haven't edited the HTML in any way other then changing the city/state.

Does anyone know what I need to look for in the HTML to make the weather icons show? Here is my LS folder, if anyone could take a look at it and let me know what the problem is, I would be grateful.
