Hi guys, this might or might not be entirely off topic. I am looking for a solution that would in a civilized manner allow me to gather photos and maybe videos from a bunch off poeple.

Background

There will be an anniversary at our local community and we are preparing a printed publication. Due to us being a bunch of incompetent, naive fools, all photos are spread across our memberbase. We don’t have any collective storage or album.
We want to use these photos for our publication, thus we need to collect them from our members and to make things worse, it is really on short notice, we have like 14 days to pull this off.

What do we need right now?

• Online upload
• about 50 users
• ages from teens to seniors
• mostly Windows users, mixed Android, iOS and dumbphone
• possible mobile app
• Anybody with URL shall upload and edit folders
• Shouldn’t need to create account or log in
• preferably folder structure (no AI sorting nonsense)
• total size unknown - my estimate is <100GB
• I don’t care right now if it is FOSS or not

Right now preferably not self hosted

Wrong community, I know. But, my home server is not accessible outside LAN and I am afraid that I wouldn’t set VPS fully working in time. I would be very happy and grateful for both advice for our current situation and for (FOSS) selfhosted solution we could use in the future. Hopefully I can finally convince everyone, we really need at least NAS, so there will be no next time… Cheers
