Tumblr makes it difficult to change your avatar…
Tumblr seems to have the ability to make even the simplest tasks an annoying chore. If you are having trouble changing the avatar (profile picture) for your Tumblr blog, follow these easy steps…
- Go to www.tumblr.com/settings…
- On the left, below “Apps”, click on the avatar (and blog title) you want to update…

- (Your URL should now be something like ‘tumblr.com/blog/your_username/settings’)
Click on the button titled ‘change avatar’ at the top of the page…
- Choose your file…
- Hit the ‘save’ button on the top right (which will now be blue)…

- Blam! Your done
