They can use a different platform

not if they already committed to this one. you can't make such a change in a few minutes. limitations are so unusual that nobody would expect them and be prepared. and even if they were known ahead of time, you are also not expecting the kind of situation where you have to upload pictures in the middle of the night.

They are pictures. They can skip them. They can run the event without it. They can print the photos on paper and hand them out. They can hand-draw posters, like everyone did in the 1700s. They can cancel the event. They can postpone the event.

This isn't a 911 dispatching system.

if they are a business then none of these alternatives are acceptable. they could loose customers over this. and surely you are joking with cancelling or postponing an event over this. please try to be realistic. you have to consider that in our society we have come to certain expectations. these may not be ideal, but closing an online service at night is a violation of that. things would look different if everyone did that, but then i'd be the one offering night service and use it to beat the competition.
