When you open a tumblr image into a new tab or window, this extension auto-loads a larger image version if it's available.
This small utility allows you to easily load and view the large version of images on various tumblr.com blogs.
Sometimes trying to zoom an image will just redirect you to a different site!
With this extension running, just right-click and choose "Open image in a new tab".
It checks if there's a larger version available on tumbr and will navigate to it if there is.
