Site is loading slow

[wallpapers]

Hello everyone.
'
My site is loading very slow.
when i loading my page the first thing i see is the background color.
Then i must wait 30 seconds before the whole page is viewable.
I'm using 1.7.2 version of 4images.
It's no for so  days now.
The subdomains on my host are loading perfect.
you can see what i mean at http://www.tuned-cars.net

I hope somebody can help me 

PS: If someone needs more information please ask.

I guess its something to do with your javascript...by disabling the javascript in the browser, page loaded in 0.5 second.

Solved 
There was a image not loaded (in javascript  thanks V@no)
I deleted this image and the site is loading again very well
