 * We are using Total Cache plugin for cdn hosting of images. I noticed that when
   we re-crop the images their filenames do not change. This becomes problematic
   for the cdn because then we have to manually invalidate them for them to update.
 * What do you think about adding an md5 hash to the image filename after every 
   crop. This way everytime it gets updated on the cdn it wont require invalidation?
 * (I believe this is default behavior for editing attachments)

 * I too have run into this issue. Adding an option to update the filename after
   a crop would be perfect.
