Jordan,
Sorry about that. Looks like a silly bug on our part with the custom image option in the SCLogin module for the Google image. To fix, please edit the /modules/mod_sclogin/helper.php file. At line 284, you'll see:
$params['googleLinkImage'] = $goLoginButtonLinkImage;
Update that to:
$params['goLinkImage'] = $goLoginButtonLinkImage;
Do the same at line 308, which is for the Reconnect buttons (when a user is logged in and hasn't already connected to Google).
Let me know how that goes, and sorry for the trouble.
Thanks,
Alex
