I don't know about this version of the site software.
With the last one, we got something like 30mb and when it was full you could not post any more. You could pull up a page of all of your images stored on BC. From there you could edit. I haven't seen anything like that here.
When you looked back at those posts, there were now lots of messy looking text placeholders instead of photos. Photobucket users suffered with this when they went fully commercial. A vast number of good posts were defaced as a result. That we had to suffer this in the course of an upgrade to BC as well was a bit of a bummer seeing as it was "our" site.
It was not much of an issue then because the new site had 500mb of image storage. Of course people can take higher resolution photos with every advance in tech and the files can be large.
I was wary of this happening from the start so I routinely size my images to get the smallest file possible. Even so, I have used half of my storage by now. I will be asking for more at some point. If I can't get it I might consider unsubscribing rather than deface my own posts again.
It's a good question.
@ped or @charic might be able to answer it. Maybe it's worth asking in the Site Issues topic.
