Display Thumbnail Preview for PSD, PNG, PSP, and More In Windows Explorer

Windows Explorer only supports thumbnail preview for several image formats by default such as JPG, BMP, GIF, and some others. This answers the question of why some image types like PSD and PNG can't be previewed in thumbnail mode even though you can view them in Windows default image viewer. This is where Thumbview plays the role.

It simply add other 19 image formats to Windows explorer. Once installed, you'll be able to view them in thumbnail mode without restarting Windows. An informational tooltip can also be seen if you hover your mouse over each image.

The developer provides two versions which both can be downloaded for free: ThumbView and ThumbView Lite. The main difference is that the ThumbView is created for programmer, and the another is for normal user who just want to automatically display in thumbnail the 19 image formats unsupported natively by Windows explorer.

The images that are supported by this program: .cut, .dcx, .dds, .mdl, .mng, .pcd, .pcx, .pic, .pix, .png, .pnm/.pbm/.pgm/.ppm, .psd/.pdd, .psp, .pxr, .sgi/.rgb, .tga/.vda/.icb/.vst, .tif/.tiff, .wal, .xpm.

OS supported: Windows XP/2003/2000, but may or may not work on Windows Vista
