here’s the code:
<%= link_to tag("img", { :src => "/images/logo.png", :alt => "logo"}, false), {:controller => 'frontpage', :action => 'index'}, :class => "logo" %>
the output:

‘(/)’
the ‘(/)’ –minus the quotes, come at the end of the image
Are you sure you don’t have that floating in your HTML somewhere?
Also, you’re doing a lot more work than necessary:
That’ll automatically assign “Logo” as the alt text, and assuming you’re using RESTful routes, that
frontpages_pathhelper will already exist.
