How can I enlarge Tumblr user avatars?
The option that enables enlarging of Tumblr avatars is disabled by default when you first install ‘Missing e’ or update to version 1.5.7+. To enable it, you need to go to the settings page (find out how) and enable it under the Dashboard Features tab, in the Magnifier section. When the option is enabled, Magnifier adds a icon to Tumblr avatars (in the dashboard and in follower/following lists) that appears when you hover your mouse over the small avatar image. Clicking on this icon enlarges the avatar image without leaving the current page.
