Function error on wp-admin login

Hi folks,

I am having some issues with a website using the ultimate branding plugin.

When you visit http://www.qualitycuisine.co.uk/wp-login.php you will see the following error:

Warning: getimagesize(/vhost/vhost11/q/u/a/qualitycuisine.co.uk/www/wp-content/uploads/ultimate-branding/includes/login-image/login-form-image.png): failed to open stream: No such file or directory in /home/qualityc/public_html/wp-content/plugins/ultimate-branding/ultimate-branding-files/modules/login-image.php on line 97

It looks to me like this may have been caused by moving the site from one server to another but I am not certain how to fix this in this specific case.

Could you possibly point me in the right direction?

Cheers
