New title rejected

I am trying to get my short film listed on IMDB but have been rejected twice. I have uploaded photos from set including BTS and still images but not sure what else I can upload to prove its validity as the project isn't on any other external websites. I thought it would be sufficient to add a link to one of our actors IMDB pages, who has uploaded several photos from the set to his page - but this was also rejected as IMDB can't be used as a link. I thought this would work because if the actor was willing to upload to his page surely that speaks for the validity of the project? Any suggestions from anyone at all as I'm not sure what else I can do. I feel like I've seen many shorts on IMDB that seem to have very little information provided yet get approved.
