Perhaps it is all those large images. Can you shrink them down? It took over 30 secs to load on my connection.
I prefer a none Adobe product to do quick and dirty image manipulation (irfanview.com) and then save as jpg/png at whatever quality you think achieves reasonable results.
i kinda thought the jpg portfolio images were seperate... but they are inside the swf file? why are there external copies of the jpgs exported then?
