If it was the graphic of the three monitors hatching with another pic in each corner that took a while, or was it the buttons along the left hand side?
From the way you're talking, it sounds like it was the photos of the animals on the home page. If so, that can be fixed easily.
:After I got to the main page loaded it was fine , but that opening page took awhile.... But they were great photos.... I think you should probably leave it becuase it is a good opener.. hard to decide it took about 45-60 seconds to load
