is a custom tag that uploads an image from a specified form field, and resizes it based on specified criteria. It has the ability to create thumbnails dynamically, to a specified width. It stores the created images in a user defined directory.

Notes:

     Prefix is text that is attached to the front of the file's name. This is to differentiate the full size image from the thumbnail if they are stored in the same directory. The thumbnail is by default named sm_yourfile.
     CF_AutoResize returns two variables, #photo# and #thumbnail#. #photo# is the filename of the fullsize image, and #thumbnail# is the filename of the fullsize image with prefix prepended.
