What does it do?
This script creates a DIV element with links to in-link URIs, which pops up on mouseover. Care has been taken to minimize discomfort. The first link displayed it the original link, the popup disappears on mouseout, there is only one pop-up at a time. Go to http://drop.by/user-javascript-direct-link/ for a demonstration.

What's the point?
Many web pages have links which either redirect you to another URL, or embeds the target page in their own frame. There may be several reasons to go directly to the target URL; avoiding ugly frames with ads, not wanting to contribute to the statistics, or lowering load times. Even worse is that some pages only deliver the target page with a certain probability.

Works well for e.g. google images. (Gives direct links to original image and the page the image is on).
