THUMB lets you preview Cascoly Puzzle Set Images one set at a time.  These 
image sets are primarily for use with the Cascoly Puzzle programs. Images 
can also be used in screen savers, as wallpaper, or included in other 
programs as clip art. Images are supplied in either VGA (320x480x256) or 
SVGA (640x480x256) format. 

In this program, the images are significantly reduced and a common palette 
is used to show all pictures at the same time.  The actual pictures, 
available upon registration, from Cascoly are full screen, with individual 
customized 256 color palettes.
