Upload avatar from URL shown even though you can't (fix completed in vcs)
Upload from your machine
Upload from URL
Inclusion of remote files is disabled on here, as per Yuriy, so the feature shouldn't be shown if this is the case. Otherwise when a user tries the "Upload from URL" option they get:
"Avatar could not be uploaded."
Comments / History
