How to render asp image tags in masterpage/page layout?

In my .html page layout file, I have this code

    <!--<asp:Image runat="server" imageurl="<% $SPUrl:~sitecollection/Style Library/en-us/help.gif %>" alternatetext="More information" />-->

And then in the rendered client side result, if I view the source of the page, it looks like

    <!--<img src="/Style%20Library/en-us/help.gif" alt="More information" />-->

and the comments prevent it from being parsed into an image. How can I fix this?

Thanks
