10 attachments, especially if you have a lot of screenshots is not a lot. Take for example USC 2.x. There are 16 screenshots and the zip file. The bigger and more complex the modification is, the more screenshots are needed to explain things - especially if it is a major upgrade from an existing popular modification. Even with the first post reserved, you are limited then to 20 attachments. If you still need more, then you need more posts reserved.

Some modifications also require things like a FAQ which isn't in the main post as it would make it excessively long (remember there are only so many characters you can fit into a post too) and if there are lots of changes made to it then a seperate change log is also often needed. Depending on the modification you might actually need 4 or 5 posts to contain all the information and keep it in a structured format.
