Custom Logo on Portal

I have a custom logo which i want to replace login-logo with in the Login page of Bonita Portal.
I am using Bonita versio 7.1 .
Could anybody guide me how i can change the logo?
Also i get an error when i try to import a new look and feel which i was using in version 5.10.?
I receive the following error:
"An error occured,please check the zip file structure ".
Any help on this would be really welcome.

Regards,
Sanjeev
