Passing parameters via URL -> static page

I would like to know how I can pass parameters to a static page via URL. It will be like this “http://www.mydomain.com/?user=username”.

How can I parse “user” to use it on a static page?

I want to use it this way:

<img src=”http://www.mydomain.com/mygraphicimage.jpg”&gt;

Any help would be greatly appreciated.
