Hello Drex, 

Thank you for asking about organizing a photo contest. I am chiming in to provide some additional resources that can help you set up a photo contest. If you would like to apply for a rapid grant we have created specific applications for common types of requests. We also have a photo contest toolkit that can help you get started in organizing a photo contest. 

Hope this adds nicely to the resources Florence, Lily and Felix have already provided. Thank you all for answering Drex's questions. 

Best regards, 
Woubzena
