MrSID with CRS

[TimE]

Hello,
I'm working on rolling in MrSID file support to an existing surveying program, and I was wondering if there are any example files with a related CRS.

I'm planning on allowing users to enter the latitudinal and longitudinal bounds of the specific area of the image they'd like to pull out of a larger MrSID file, but I'm finding it hard to test this without a MrSID file with a CRS. I'm not exactly in the position to generate this either, so as long as I have some kind of picture with - CRS I should be golden to test.

I believe NAIP imagery can be downloaded free of charge:
