[OSM-dev] Tile stitcher?

[Alan Mintz]

I've slowly been gathering USGS urban tiles for the areas in which I'm 
mapping (taking care not to bog down the server) with the ultimate goal of 
having a backup tileserver, since the MSRMaps.com (fka Terraservice.net) 
server seems to be poorly supported and is prone to long periods of 
blackout (like today) or other problems.

Before I embark on the somewhat daunting project of a full-blown server, I 
just want to be able to stitch some of these 200x200 pixel, 0.25m/pixel 
images together into larger images that I can load as background in JOSM 
(using PicLayer).

Is there a simple, hopefully command-line or config-file driven tool that I 
can use to generate a single JPEG from multiple JPEGs?

What I've wasted time on so far are tools that are either intended to 
create panoramas, warping the images in the process, or random mosaic 
generators. Neither type of tool seems to be able to just line up images 
side-by-side.
