Photo contest where participant cannot vote for their own submission

We would like to start running photo contests where our employees either upload their own photos or we upload all of them. We then want to invite them to vote for the best photo. Is there a way to stop people from voting for their own?

Hi,
Sorry, but at the moment there is no way to prevent users from voting for their own images.
I will add this to our feature requests.
Kind regards
Philipp
