Now available for download is a new revision of ThumbGen.

I've taken the time to convert it to .net 2, fix some annoying UI inconsistencies, give better progress feedback when creating thumbnails and also wrap it all up in a nice installer. 

If you've never used ThumbGen before it is a utility for Windows XP & Vista that allows easy creation of thumbnail graphics.
Just drag your files onto the ThumbGen file list, choose your image size, filename prefix or suffix and the file type then press Create Thumbnails.
Thumbnails of your chosen images will be placed in the original images folder.

Available for free from my Desktop Enhancements download area.
