Hiding submitted photos until voting starts

I thought there was a way to hide submitted photos until voting starts. Right now, people can see the previous submitted photos. I want to hide them. Can I do that?

Thanks.

Hi Robert,
In the wizard step 4 (advanced) you can set allow voting. Below there is an option to set voting start and end date.
If you set this, you can also chose to hide images before the voting period starts.
Kind regards
Philipp

Another idea could be to use the approval dashboard.
