was on about yesterday.....enjoy!!
<!---(Function:
ThumbIt)------------------------------------------------------
Date Created: December 1, 2003
Author: Bryan
Arguments: FileLoc - full path of image to be thumbnailed (string)
required
ThumbPrefix - string to append to the filename to name the
thumbnail (string) not required
ScaleBy - which dimension to scale by "W or H" (string)
required
ScaleValue - the measurement of the dimension specified in
ScaleBy to use to calculate proper scale (string) required
Purpose: shrink an image
Returns: N/A
