How to show an image based on referring url

[Mike Stunn]

Hello, I have been trying to find a piece of code which would show an image based on referring url.

How would I go about displaying say Image1.png if a user came from "http://www.mysite.com" ?

and if else they came from somewhere else how would I display a default image?

any help would be greatly appreciated on this matter as this is nowhere to be found online.
