The problem was in our build. I was using external libraries for the images instead of the built in libraries. I still haven’t gotten everything to work, but I do not believe it is a problem with GDAL. <BR>
<BR>
The version running at <a href="http://mapservice.swc.state.nd.us/indexmap.phtml">http://mapservice.swc.state.nd.us/indexmap.phtml</a> has GDAL 1.2.6 and the raster images work fine at all scales for some counties and not for others. We are looking into the problem assuming it is due to the clipping process, since most the counties we have clipped to the county boundaries do not function properly. For instance, McKenzie, Mountrail, Ramsey, and Benson counties do not display correctly at all scales, but Billings and Burleigh look as they should. All those counties have been clipped with ERDAS. Every county that has not been clipped display as I would expect, no matter the size. <BR>

Paul, <BR>
<BR>
I'm afraid I don't know what is going wrong. If you are handy with a <BR>
debugger, then you could run shp2img, break it when it hangs, and <BR>
get a traceback with the "where" command. <BR>
<BR>
Alternatively, if you are in a position to provide "ssh" access to your <BR>
machine, I could do some investigation. <BR>
<BR>
Best regards, <BR>
<BR>
