Tumblr Post by DavidC

This extension lets you post photos, videos, mp3s, quotes or links to your Tumblr account by right clicking on the stuff that you want to post and then click on the associated "Post to my tumblelog" menu item in context menu that pops up.

By default content will automatically get posted to the tumblelog you've selected. However, if you want to attach the optional values for each content type, like sources for the quotes, captions for the photos and videos or descriptions for your links, you can set the extension to popup an input dialog for the types you want to specify the optional values for.

When you post content to your tumblelog the extension will check if the text is a link to a Youtube video, or the raw embed-tag from any video site that can be embedded into your tumblelogs. If it finds a match on any of the above criterias the text will be posted as a video entry instead of text post which is the default type for selected text.
