-redacted- I didn't see the second page. :/
It is weird though. I've used the "upload file" button in the posts before and there is no media in my media storage on the site. So, when you use the "upload file" button it shouldn't matter that your storage is full...
Have you considered using a separate hosting site for the time being, like photobucket? If you have a smartphone that you take the photos with, photobucket has a pretty good app, much better than their website.
