Windows hosting and No Thumbnails

[dotman]

Hi,

Unfortunately this blog has to hosted on IIS. I've confirmed they have the GD Library installed, but still not showing thumbnails. The blog is installed in a sub dir, so it may be a path issue. I am using "thumb" for the custom field. Could you take a look and help me sort this out?

BTW, I just installed the theme, so I currently have only updated the first two articles with the TN custom field for "Energy and Environment" under the tabber.

Update: Just wanted to add that I tried taking out the domain from the custom field and am checking permissions now on these files/dirs:
tools folder
tools/cache folder
timthumb.php

Thanks,
Doug
