1 entry means 1 photo upload.ACCEPTABLE ENTRY
If you have entered an elaborate wedding cake that is many layers and different cakes, all making up the 1 wedding cake. This can be entered, because although it is comprised of many layers and different "cakes" it is technically 1 cake.
Only upload 1 photo though.UNACCEPTABLE ENTRY
If you have 2 completely different cakes, you cannot enter both. Choose which one is your favorite and only enter the 1.
You are only allowed to enter 1 photo period. Some people will use a graphics program to show multiple angles of the cake in 1 photo, this is also acceptable.
The point being, you can only upload 1 photo per contest.
