MAKE VIDEOS SHOW UP IN YOUR TUMBLR DASHBOARD!
Get your browser add-on for Firefox, Chrome, or Safari, and visit the Tumblr Video Thumbnails add-on page for information, installation help, and more. Special thanks to our friends at Vimeo, Blip.tv, and Wreck & Salvage for their testing and support.
The add-on was created using Mag.ma, our own video aggregation service, to do thumbnail lookups for numerous video platforms (not just YouTube) with our simple API methods. The results? Uniformity for Tumblr users and creative support for content creators.
