2htdp/image uses the save-file method of a bitmap% to do the actual saving and it appears to not support different DPIs.
http://docs.racket-lang.org/draw/bitmap_.html#%28meth._%28%28%28lib._racket%2Fdraw..rkt%29._bitmap~25%29._save-file%29%29 If it were extended somehow, then I imagine it would not be difficult to provide you with a little function that was like 2htdp/image save-image, but that saved the DPI you wanted. But maybe post-processing is easier? You could script that with the process* function, too....
