Nice script, work very good, I really like it.

It does work good.
Helps to weed out fake thumbnail images on videos from "YouTube Partner" users who like to scam people into clicking on their videos so they can increase the amount of hits/views their video gets.

But it does not for videos listed under "subscriptions" when you are signed in and trying to view the new YouTube homepage.

**Add The "Youtube Related Videos Like/Dislike Preview" Greasemonkey script to this script and you will be able to avoid clicking on videos with MISLEADING TITLES also. Because it adds a green/red meter next to each video on the right side, you can then see if a video's title is bullcrap before clicking it.

It really does work on EVERY YouTube page now, including playlists and Feeds. Thank you so much. Youtube is constantly changing its layout, so I hope that you will always be able to keep this up to date. Thanks again.

can you make it animated when only mouse over?and make the right thumbnail bigger..that will be cool...

Really useful script. Now you can avoid getting Rick Rolld

Some would think that having thumbnails animate through three images would be annoying. But I think it's actually kind of fun to watch.

The best thing about this script is that you get more than just that single, often plain, image that is supposed to represent an entire Youtube video for you. Many times it does nothing for you and the only thing you have to go by is the title of the video. Well, this doesn't only liven up Youtube pages, but it also lets you see two more frames of a video, and it even helps you from clicking on those annoying Rick Rolls.

Animated thumbnails usually come packaged with other features that you may or may not need, and there are some that are by themselves but none of them work anymore. This script is good if you're an organized person that doesn't like too many other features that you can live without.

Thanks for making it, JoeSimmons. It's pretty cool.
