I'd probably not use url_for() here, it's slightly slower and it makes little sense since it's an external url.

ok, I just removed all references to url_for, but can you explain me how to use [action]_[controller]_path thing? I do not understand =(

the _path thing is rails' resource routes.

I meant, no need to use url_for when all it really needs to build is a string, alá "http://gravatar.com/gravatar?user=#{foo}"

yes, I understand the _path thing now

I did the url manually

do you have another suggestion?

thanks
