Greg - You create a map file with one LAYER for each resolution, all members of one GROUP with the same name, and each layer having a MINSCALE and MAXSCALE setting so only one layer of the group at a time is displayed. If you're not familiar with those capitalized keywords you should do some reading on them - you can also find other discussions in the archives on this topic by searching on those keywords.

I want to be able to zoom in, zoom out, and pan through this imagery, and have MapServer display's at any given time be from the GeoTIFF that is most appropriate, based on the current zoom. How can this be done with MapServer? Greg
