I just register only to show you what I did to show thumbnails in vista 64 (tga, psd, an many others)
Download this file:http://www.uproar-in...urThumbnail-v1.0.exe
Second Step: (No needed on Windows XP but is neccesary on Vista)
Create a shortcut on your desktop with this info:
%SYSTEMROOT%\SysWOW64\explorer.exe /seperate, /select, c:
After that the explorer will open your C root, you can change the path to point to your Tga files for example, whatever you do from now on you could see your images inside windows explorer.
I hope this help you ..., for me work like a charm ...
