We've all been there: You see an image on the internet that you'd love to share, whether via a forum, your blog, or your (ick) MySpace profile, but the whole process of saving an image, then uploading it to a hosting service, then finally getting the new URL and embedding the image is a pain. But, as a card holding citizen of the internet in good standing, you also know better than hotlinking images from other people's sites. So what's a busy surfer to do?

Web site ImgRed (Image Redirection) lets you quickly embed an image from another web site and embed it elsewhere without leeching bandwidth from the source. Just grab the URL of the image and append it to http://imgred.com/ (e.g., http://imgred.com/http://example.com/pic.jpg). The site copies the image to their server the first time it's requested, then serves it up permanently. Handy. — Adam Pash
