Photo gurus, need advice/assistance

[derf]

When I was 16 I had a house party and I fucked up a photo collage of the capitol building that my parents had taken. Today I went back to DC and took some crappy cell phone shots and put it together.

What would TWF suggest as the best way to get these printed out on photo paper. I know they are not perfect and don't exactly match up, I took them with my cell phone and pieced them together in MS paint. I do not need a perfect quality photo job, and what I have is good enough.

Anyway, whats the best way to get these printed out in a decently large size, something near 20" across for the wide shot?

While piecing these two photos together I also discovered that the largest size photo that MS paint can handle before it locks up my computer is 114728 x 70806. I had all the photos from these two pictures, plus a third version, plus a few extras that didn't come out good on one sheet and it locked the damn computer up.
