Now this is probably something that a typical user never has to think about…previewing TGA images and Photoshop files. However if you’re like me and use Photoshop a lot, or happen to like taking your World of Warcraft screenshots in TGA format (which is superior to the default JPG), this program is a godsend.
MysticThumbs is a thumbnail extension for Windows XP, Vista, and 7 (both 32- and 64-bit). It currently supports PSD, TGA, DDS (a game texture format), PAA, and JPEG2 file formats. All that you have to do is install the program and you might have to restart your computer. Best of all, it’s completely free.
This is a fantastic find for me, since I no longer have to hesitate taking tons of screenshots in WoW, because now I have a much simpler method to sort through them later. I just installed it and I love it already.
