Why use this instead of https://twitter.com/username/profile_image?size=original ?

Doesn't seem to work, tried with my handle and getting a bad url.

https://twitter.com/uptownhr/profile_image?size=originaL

Try with a lowercase l:

https://twitter.com/uptownhr/profile_image?size=original

Also, why is this not documented anywhere?

I found this but doesn't use the username... https://dev.twitter.com/overview/general/user-profile-images...

Well, it's documented somewhere... I'm not sure where I found it, though!

haha thanks! Do you know what options are available? How do I get the 25 by 25 version?

?size=normal does it

try out, http://images.jlee.biz/tw/jason

would you use this?
