Too busy looking for TidyPics settings' code but the general code is:

                    $current_role = roles_get_role($user);
                    $current_role_name = $current_role->name;
                    if ($current_role_name == 'DEFAULT') {
                          HERE_IS_TIDYPICS_ACTION
                    }

It's an action for TidyPics plugin or your own theme/plugin

Thanks RvR, though this isn't exactly what I intent to do, but usefull anyway, so thanks :)
With this code I can check what someones role is and do an action.

But I actually want to check what their image count in tidypics is and do an action according to that number, if it's under 5, I want their role to be set to 'novice' or something simmilar and do nothing if it's over 5.

Well, then additional to above code you need to set user' role as:

                    $current_role = roles_get_role($user);
                    $current_role_name = $current_role->name;

                    $new_role = 'PRO';
                    if ($current_role_name == 'DEFAULT') {
                          HERE_IS_TIDYPICS_ACTION
                    }

                   else if (HERE_IS_TIDYPICS_ACTION_VALUE && $current_role_name !== 'DEFAULT') {

                      roles_set_role($new_role, $user);

                  }

I don't check it but think that all correct.

Try it.

Hi RvR, sorry for the late reply, but..thank you! :)
