hey thanks!

in case anyone wondering, it also works with windows7.

Yeah it's a great plugin, I've been using it for ages. I didn't quite understand why windows wouldn't thumbnail targas seeing as though it's a pretty standard format

thx very useful plugin ^^

I'm using ThumbView Lite and it works perfect...also shows DDS and various other usefull file format. Together with LionT's 3D Shell extension the 3dgs workflow can speed up quite a bit
