How do I save my avatar to upload onto Deviant Art so that its still animated?

Right-click and save image as "jbkidmarvel.gif" to your computer.

Then, upload it to Deviant Art (I guess - I'm not familiar with the site).

I tried that but it says my avatar isnt "50x50" and wont upload

That's because it's 75x75 here. That's the information I needed to help you with.

Use this one -

Thanks a lot Gary
