Attached is the kit previewer.
To install, unzip anywhere on your computer. The .dll file must be in the same location as the .exe. Then simply make your kit in PNG format, and call it kit.png and place in the .exe directory.
There are likely to be bugs, especially with those people using Vista, as I'm testing on XP, and knocked this up in an hour or so, so didn't really do that much testing.
Hope it works.
Cheers,
Tom
