I have a huge image (234 megapixels) I want to plot in a way that it is dynamically resampled depending on the size of the area the user wishes to see. Is there any tool that supports doing this, or will I need to do this myself?

Typically the techniques to do this are referred to as (Image) Tile Rendering. Basically this is how applications such as Google Maps work.
A quick search on google turned up an OpenGL library for doing this for you (http://www.mesa3d.org/brianp/TR.html). I’m sure there are others that you should be able to discover if this library doesn’t fit your technology needs.
