4 times vertically is 4 times your image height, 2 times horizontally it's 2 times your image width. so let's say your image is 120px W/100px H you have now image 240px W/400px H.
In HTML you can open a div, with style that gives it a size and gives it your image as a background.
the div...
HTML:
<div id="img-repeat"></div>
and the CSS...
HTML:
#img-repeat {width:240px; height:400px; background:url('your image url here') repeat;}
That's it,
enjoy!
