Actually, you can link directly to images, but you have to use another source. I should write some PHP code for Atlantic storms to get that sometime...it's a PAIN to type in manually.

Here is how to do it:
wwwghcc.msfc.nasa.gov/cgi-bin/get-goes?{args}, where args are described on this page: http://weather.msfc.nasa.gov/GOES/getsatellite.html

I usually pull the Lat/Lon off the latest Recon or NHC report. It's unfortunate that you can't just do a conversion from POST to GET to grab the info and make it work, but the POST page sends click coords whereas the GET page requires Lat/Lon, plus the POST page sends everything uppercase (required to work) and the GET page requires everything lowercase (why couldn't they just do a case conversion in their CGI so both work both ways?).
