I don't know...? According to my account info, I'm currently using only 0.8% of my alloted quota, and the pictures are between 24KB and 72KB, so not that huge. The biggest of them is roughly 600x800 pixels in size. And I'd never reach 300,000 characters, omg, how does anyone LOL?

I'm truly stumped. And a bit sad, because images make a text much more readable and entertaining.
