This scripts claims to be able to redirect directly to the image file of various imagehosts. The idea is good as the amount of clutter is ever increasing when looking at image files.

Which is also the reason behind the basic problem with the script. Imagehosts are simply evolving too fast for a static script to be able to do the job for you. Furthermore the original author of the script has abandoned it. Both of these points leads to you having to maintain and update the script yourself.
