Image_tag in options_for_select in rails

This is my code

<td> <%= select_tag "options", options_for_select( [["Show",
"/registrars/"+registrar.id.to_s],["Edit", "/edit_registrars/"+registrar.id.to_s],
["Dashboard"开发者_如何学Python, "/homes/"+registrar.enrollment_application.id.to_s], **
[image_tag("file_cabinet.png"), "/registrars/"+registrar.id.to_s]**, ] ) %></td>

I want to use this

<%= link_to(image_tag("file_cabinet.png", :border=>0), :action => :show, :id => 
registrar, :filecabinet => true) %> 

In above code if you see I tried but it is not working , any ideas??

You can't nest an image tag inside an option tag.
