Harald,
I use ImageMagick/GraphicsMagick to resample HUGE high resolution tiff images to something more manageable to work with. Using a script, I converted hundreds of images to lower resolution copies. Then it was simply a question of pointing ConTeXt to use the appropriate directory to find the right figures.
The basic comand is
convert -resample 300x300
(or 100x100) and you can play with "-quality 75%"
This can be done once and is much better than getting ConTeXt to convert every time on the fly.
texnically ConTeXt mkiv could be able to convert images with swiglib and GraphicsMagick see https://swiglib.foundry.supelec.fr/ It should work under linux64 and windows (and yes, I'm looking for Freebsd support...)
