change apperence page based on link to the page

Is it possible to change the apperence of a page based on the link to the page. For example:

Page http://www.yourdomain.com/test
Link: http://www.yourdomain.com/test?picture1
Link: http://www.yourdomain.com/test?picture2

The page itself must be the same but the picture that is shown must be different. Is this possible?

I want to use it to link from a newsletter with a variable in it. For exampe http://www.yourdomain.com/test?picture%numberpicture%
