Cant fix login with facebook pic

HI,

I installed JFBConnect and everything working perfect but I would like to make a few small changes. Problem is that on the button "Login with Facebook" does not show Facebook logo. I would like to make a smaller space between the title "password" and the form . I would do the same for the title "username".

Please if you can help me to solve the problem. I tried to change the code in helper.php

if ($ picWidth> = 100)
return "large";

but it does not solve the problem.

here is the picture what I want to solve. Thanks and sry for bad english.
