Re: Database size
That's going to depend on the number of images, replies, and etc. The images are not stored in the database, but the info about them is, along with replies and such. And just to give you an example, I have 11,000+ images on my personal site and the images table takes up 1.6mb. Though none of the images really have any descriptions or additional info about them, so the space would be a little more if you add those things in.
