There are already thousands of images in the componentpack; the point of it is to have one set of images, so players can download it once, and use it in many many mods.
Also so that modders have an huge instant image selection while making their mods.
And, also so small-time artists have a place to put their stuff where it will be seen and used.

I don't recall offhand what rez they are exactly (haven't made any images yet), and I've got to run off to work, but just opening a screenshot in a basic image editor should allow you to count the size.
