r/GoogleForms

I'm looking for an alternative to Google Forms that will allow a respondent to fill out a form, and attach a picture, and respond. It seems this cannot be done easily with GF.

Backstory is we are thinking of running a scavenger hunt, and a contestant would be required to fill out a form stating they met a condition, and attach a photo proving it. The responses and attached photo would then be compiled and evaluated on my end.

Any and all ideas would be appreciated.

Thanks
