So I don't think it's a problem caused by...

...I do this, the image viewer obviously becomes the active window, but I would really like to retain R as the active application to avoid having to toggle with Alt+Tab or the mouse to make R active after loading each image.

I installed the (binary) biOps package, which can use libtiff and libfftw. Then I used macports to install the libraries (in /opt/local/lib).
