Imageshack New Feature: Upload from URL

This is a new feature which i have been observed for quite some time. I never use it till today, where i found it rather useful when you need to use photos from the net(such as the previous post, Happy Birthday Answer.com!). I can transfer the file from amazon to Imageshack without having to go through the hassle of saving the pic into my comp first, then upload to imageshack which i found it... Excellent!
