wickedpdf not rendering images?
<p>i am using <code>wickedpdf</code> gem to generate <code>pdf</code> <code>invoice</code> from the <code>html</code> code.</p>

<p>gems:</p>

<pre><code>gem 'wicked_pdf'
gem "wkhtmltopdf-binary"
</code></pre>

<p>gemfile.lock</p>

<pre><code>wicked_pdf (1.0.6)
wkhtmltopdf-binary (0.9.9.3)
</code></pre>

<p>in controller:</p>

<pre><code>  def show_pdf_invoice
    respond_to do |format|
      format.html { render :layout =&gt; "pdf.pdf.erb" }
      format.pdf do
    render pdf: "show_pdf_invoice", :layout =&gt; 'pdf.pdf.erb'
    #render :pdf =&gt; "pdf"#, :layout =&gt; 'pdf.html.erb'
      end
    end
  end
</code></pre>

<p>in <code>views/invoices/show_pdf_invoice.pdf.erb</code></p>

<pre><code>  &lt;img id="image" src="https://www.google.co.in/logos/doodles/2016/holidays-2016-day-2-6356741311692800-scta.png" alt="logo" /&gt; 
  &lt;%= wicked_pdf_image_tag 'https://www.google.co.in/logos/doodles/2016/holidays-2016-day-2-6356741311692800-scta.png' %&gt;
