  # # MOD Title: Click Image Resize MOD
  MOD # # Author: Sllohcin <staff@toynexus.org> (N / A) http://www.toynexus.org
  # # MOD Description: This MOD resizes any images "inline" that are greater than a set width (default is 300px) so as to constrain them to the September said width (create a pseudo thumbnail).  One may then 'click' the thumbnail to enlarge the image and then click it again to shrink it back.  Any images that are smaller than the set width are not affected nor are any cursor changes applied to them.  This only affects MOD images posted via the [IMG] tag.

So where does this come in use! Reduce size of images, but in what.

I think the code is about reducing the images size on the web pages.
