Contest plugin – 1 vote per IP

Hi,

I’m looking for a contest plugin.

We have un selection of products (images + description)

We want to set up a voting system where users can vote only once : just for 1 product (and not once per product)

I found this plugin : https://galleryplugins.com/photo-contest/ which is great. But it’s not possible to vote just for 1 picture ??

I hope you can help me.

Thanks in advance.

Geoffrey
