Ruby and RSS2 Feed not displaying image

Question

Trying to create a simple RSS2 Feed that I could later pass on to FeedBurner but can't get RSS feed to display images at all.

Also, from what I have read having xml.instruct! on top might cause IE to complain it's not a valid feed. Is this true?

My Code looks like

xml.instruct!

xml.rss "version" => "2.0", "xmlns:dc" => "http://purl.org/dc/elements/1.1/" do
 xml.channel do

   xml.title           "Store"
   xml.link            url_for :only_path => false, :controller => 'products'
   xml.description     "Store"
   xml.pubDate         @products.first.updated_at.rfc822 if @products.any?

   @products.each do |product|
     xml.item do
       xml.title       product.name
       xml.pubDate     (product.updated_at.rfc822)
       xml.image do
         xml.url       domain_host + product.product_image.url(:small)
         xml.title     "Store"
         xml.link      url_for :only_path => false, :controller => 'products'
       end
       xml.link        url_for :only_path => false, :controller => 'products', :action => 'show', :id => product.permalink
       xml.description product.fine_print
       xml.guid        url_for :only_path => false, :controller => 'products', :action => 'show', :id => product.permalink
     end
   end
 end

end

Answer 1

Are your image paths relative or do they contain the full URI to the resource? Double check the source made by your script for this kind of thing. Google reader will try and correct this, but not every RSS tool will do the same.
