Photo sharing on Google Drive, other options?

So I take photos for my university’s improv team and they perform every Monday, so I get quite a lot of photos. I share all these photos using Google Drive, as I am able to access that on my computer and everyone can access the photos from the app

However, I have run into a blockade where I have run out of storage. I thought about buying more storage, however if I do so (from my understanding) the others will run out of storage since they do not have the upgraded storage like I would. I thought about looking into Dropbox, but I don’t know much about that program. I am willing to pay/im pretty sure the improv team would pay for it since I am a member and it’s a service for them they could pass down to whoever takes my position after I graduate.

I’m just running out of ideas and everything is either super costly or wouldn’t be best for my situation :(
