Customization and usage questions (changing links & multisite)

I have two different questions regarding the post voting plugin.

Customizing the template tags links.

I use the template tags to vote on a custom post type.

This is the code I use for the thumbs up image: <?php echo wdpv_get_vote_up(true, get_the_ID()); ?>

Were can I find the code for changing the thumbs up image to a text link?

So to be clear I want a text link instead of just the thumbs up image.

The same question I would have for the voting results. I want to add a image next to the results number.

This is the code I use for the results: <?php echo wdpv_get_vote_result(true, get_the_ID()); ?>

Is this possible?

Another question is regarding multisite.

Can the post voting plugin be used as a rating system for multi sites. We want to rate the different sites in stead of the different post or pages. Is this possible?

Thanks in advance for the help!
