I actually thought about that while I was recording the songs onto the tape, but it seemed to work out fairly well. Cassettes sound horrible, yeah, but since it was brand new, it's not like it had a very lo-fi quality.
Most of those images I got from an Anthropologie catalog. They seem to have very appropriate, high quality images, no matter what I'm working on.
I tried scanning it with the case once or twice, and it was sadly unsuccessful because of the glare. D:
