Redirects Tumblr Image URLs to the raw version
THIS SCRIPT DOESN'T CURRENTLY WORK! Tumblr changed something so you can no longer access the raws, I'll keep the script up for a while in hopes somebody founds out how to access them again.
Only works with direct URLs. Right click the image and press "open image in new tab" in Chrome or "view image" in Firefox.
Also works with videos!
