[Plugin: Mini twitter feed] Avatar not showing

Hello!

Great plug-in. Everything worked right away except the avatars:

I looked at the rendered code and it is calling the avatar, but it is showing up as 0 x 0 pixels for some reason? Not sure. I tested it with another user name and the same time happened.

Let me know how I can fix this! Thank you!
