You find it in the css of you template. I don't know what image you are talking about

but in css you can make an image stop repeating with the css attribute "no-repeat"
For example, a background image for your page:
body{
background: url('url/url/img.jpg') no-repeat;
}
you also have repeat-x and repeat-y to force it repeating only orizontally or vertically
I order to work to an Icy template, you have a clear example in
templates/mg_themes/style_icy.css :
/* header */
.forum-header {
background: #E8EEF8 url(images/ice/bg_top_100.jpg) top left repeat-x;
padding: 0;
}
Just change repeat-x with no-repeat and your image will not repeat anymore (watch out for "top left" that are the alignmente of the image)
(Just to be sure:
the code I provided is meant to be an example. You don't have to modify that... I don't know what image you are talking about )
