Preload Images.

[Dream_ni]

I am new in this theme. I appreciate if somebody can explain how the preload image function works, because i downloaded it, but the page is always downloading the images.

If anybody knows how to download the images before anything else in the page i will be thankfull if you say it to me.

The link where i want to put the preload images is:

Thanks for your help.
