I dont mean to be rude, but why dont you ask on the site where you purchased that module, iam sure they would have a better idea on how to start with such a project.

However if you wanted to start messing around with the file ie: change some varibles its the voteinclude.php file & or just edit the Language file with your /pics.gif , you basically leave the _whatever & put a Url in "HERE" that links to your /images/pics.gif

That Module for the moment is a pay4 Module so please dont post any code here.
