Javascript slideshow woes…

I am having trouble setting up my image slideshow for my website.
My problem is i have a image gallery with thumbnail pictures, when you click on a thumbnail i would like to have my slideshow display starting with that pic. However, i have not beenable to achieve this affect because when you click on a thumbnail it starts off at the beginning of the slideshow.

Any help will be appreciated

Here is my website if you need to see a visual of my problem and the desired affect im trying to achieve…
