Recommended free services for comic website?

So I recently finished up a comic for a school paper. I’d like to put the archives online organized by date like most comic strip artists. To name a few (and so you know what I’m going for)...

http://xkcd.com/

Problem I have no idea how to go about this. I’m sure there are some free database services and stuff out there, but I don’t even know where to look. Any pointers?
