If the id is part of your route data:

<img 
    height="660px" 
    width="430px" 
    src="<%= Url.Action("WebPageImage", "WPMManagement", new { id = ViewContext.RouteData.Values["id"] }) %>" 
    alt="bild mit webseiten version" 
/>

Well, from what I can see that URL does not contain any querystrings:

http://localhost:64075/WPMManagement/Image/id=09251a7f-c362-4ed9-98e2-c9d555aaaf4f

If you'd have a ?id= you'd be able to write Request["id"] in your view, but in the case of the abovementioned URL this will return null. In other words, the correct url in order to use Request["id"] is:

http://localhost:64075/WPMManagement/Image/?id=09251a7f-c362-4ed9-98e2-c9d555aaaf4f

However, if you're Route indicates that the part after /Image/ is the Id, you can remove the id= all together, and the resulting URL would be:

http://localhost:64075/WPMManagement/Image/09251a7f-c362-4ed9-98e2-c9d555aaaf4f

This should enable you to get the Id of the current RouteValues dictionary

should i write it in view inside id? like id=<% Request.QueryString["id"]%>?

Write it in your method behind. If you are using MVC3, then you can use the ViewBag like so: ViewBag.Id = Request.QueryString["id"];. But, it seems that adding it straight in seems to work as well.
