Ha, I finally found it!
(And what I mean by that is, I finally bothered to look it up.)
Now I know how to make my pictures big and it is super awesome. (See previous post from five minutes ago if you want an example of how I'm already abusing the privilege.)
To give credit to the amazing person that posted this info and made it so easy that even I could do it, click here.
Of course I also had to stretch out the blog itself to make room for all those pictures, but that was easy. (Go to design, edit template, adjust width or something.)
Clearly I have final papers to write...
