Voting system

Hiya Ive installed nextgen gallery and voting plugin. I have successfully added a gallery of images on my page but and I’m having trouble getting the voting system to appear.

i have looked at the faq and it says:

How do I show the voting form?

You need to add a small tag to the gallery display template.

For image voting: For image voting, add the following tag: <?php echo nggv_imageVoteForm($image->pid); ?>, to the gallery display template.

I don’t know where the template is? Can someone help me please.

When adding the gallery to the page one of options in “customise the display settings” it says Template. I have tried pasting in the <?php echo nggv_imageVoteForm($image->pid); ?> but it doesn’t work and breaks the gallery with an error: [Not a valid template]. So obviously this is the wrong place.

how do I get the voting system to show on each image in my gallery please?

Thank you
