One Ajax call, two divs to fill. How?

[x-mob]

Dear,

Two jpeg files to show in two different divs via one Ajax call, same images but one is the thumbnail. "house.jpg" and "house_thumb.jpg".
house.jpg is in div id=main, the other one in div id=thumb.
I tried everything i can but without success. Onload, Onclick... don't update the thumbnail. Any idea ?

Thanks.
