URL Linker
I didn't relaize how much I used this little javascript I wrote until I took my site offline for redesign.
From time to time I get direct URLs to images and videos. Especially with the videos, it's hard to save it to your computer if the link you receive opens using Media Player or whatever.
The script doesn't open the file for you. Instead it creates a Web page with a link that you can then use Internet Explorer's "Save Target As" command to right-click the link and save the file to your hard drive.
