Problem: With a large number of images (> 100), the coordination is very cumbersome and time-consuming.
Who would benefit: Wikimedia Commons and all participants in the Photo challenge.
Proposed solution: Improvement of the voting through a simple and user-friendly program interface.
More comments: It would be helpful, for example, if you could filter out photos that you do not want to award points in order to gradually reduce the number. It may be possible to use the same method as for "Picture of the Year". In addition, a simple integration of the images is desirable, as in my experience this is often done wrong. If it is the aim and purpose of the Photo challenge to win new participants (photos), then IMHO should also provide an adequate user interface.
