[jQuery] image caching problem

[jQuery] image caching problem


Hi folks!
I have a simple profile image upload script. The problem is that I
can't change the actual image with jQuery, because is cahed ( i
suppose ).
Only one picture allowed per users so I renamed their files to
user1.jpg, user2.jpg, etc.
I tried to use $('#somethin').attr("src", "userN.jpg"); but it has no
effect, because it was the same src before so the picture wont change.
How could I make it reload these pictures correctly ?
