What is the difference between files per PollUnit and photos per contest?
PollUnit offers two different ways to vote about pictures. Depending on the PollUnit type different limits apply.
On the one hand you can create a PollUnit voting. Here all pictures / files and voters are shown in a table. This view is optimized for an overview who voted for what. The voters are in focus. Here counts the limit files per PollUnit.
If you run a PollUnit photo contest, significantly more photos can be uploaded and managed. Here counts the photos per contest limit.
You can find out more in our tutorial Vote for pictures.
