PDF image header using wicked_pdf gem and wkhtmltopdf

My controller:

  def show
    respond_to do |format|
    format.pdf do
    #render :pdf => "show",:template => "welcome/show",:footer => { :right => 'Page [page] of [topage]' })
    #render :pdf => "show",:template => "welcome/show", :header => {:content => render_to_string({:template => 'welcome/pdf_header.html.erb'})}, :footer=> { :right => 'Page [page] of [topage]' },:margin => { :top => 38, :bottom => 35}
    #render :pdf => "show",:handlers => [:html],:template => "welcome/show.pdf.erb", :header => {:content => render_to_string({:layout => 'pdf_header.html.erb'})}, :footer=> { :right => 'Page [page] of [topage]' },:margin => { :top => 38, :bottom => 35}
    render :pdf => "show",:template => "welcome/show.pdf.erb", :header => {:content => ActionController::Base.new().render_to_string({:template => 'welcome/pdf_header.html.erb', :layout => false})}, :footer=> { :right => 'Page [page] of [topage]' },:margin => { :top => 38, :bottom => 35}
    end 
  end
end

I get the PDF along with the page numbers, but I cannot get the image title.

This is the layout:

pdf_header.html.erb

<%= image_tag  "gla/image.jpg" ,:width => "90",  :height=>"85" %>
<%#= wicked_pdf_image_tag  "gla/image.jpg" %>

As soon as I open pdf_header as an HTML file, I get an image, but as soon as I call the PDF, I can’t display the image

In console I get this

Started GET "/welcome/show.pdf" for 127.0.0.1 at 2014-04-17 09:47:05 +0530
  Processing by WelcomeController#show as PDF

Completed 200 OK in 782ms (Views: 1.3ms | ActiveRecord: 0.0ms)

The commented material is what I tried and did not succeed. Is there any other way to display the image directly in the header by specifying the image path instead of passing it through html?

Acc. official documentation

<%= wicked_pdf_image_tag 'path' %> instead of <%= image_tag 'path' %>

this should work for you

<%= wicked_pdf_image_tag  "gla/image.jpg" ,:width => "90",  :height=>"85" %>

:

def wicked_pdf_image_tag(img, options={})
  image_tag "file:///#{WickedPdfHelper.root_path.join('public', 'images', img)}", options
end
