Topic: HOW CAN I CHANGE THE LOOK OF THE IMAGE PRELOADER?

HELLO,
I WOULD LIKE TO CHANGE THE LOOK OF THE PRELOADER. I MEAN THE CIRCLE THAT APPEARS WHEN THE PICTURES ARE LOADING. I DIDN'T FIND AN IMAGE SO I THINK IT'S SOMEWHERE WITHIN THE CODE...

THX

Re: HOW CAN I CHANGE THE LOOK OF THE IMAGE PRELOADER?

Is it possibile to turn the color of that (white) to something else? How?
