Answer 1

I just overcame a similar issue on Windows with images uploaded through Paperclip, because WickedPDF's wicked_pdf_image_tag helper requires the images to be in public/images.

I used the solution given here for that problem, but I still couldn't get the images to render in the PDF. Then I discovered that if I put the image into the public/images folder and referenced it that way, the wicked_pdf_image_tag helper rendered the image tag with forward slashes instead of backslashes after the 'file://'.

This is the helper method I ended up with, which replaces wicked_pdf_image_tag:

module ApplicationHelper
  def wicked_pdf_image_tag_for_public(img, options={})
    if img[0] == "/"
      # Remove the leading slash
      new_image = img.slice(1..-1)
      image_tag "file:///#{Rails.root.join('public', new_image).to_s.gsub("/", "\\")}"
    else
      image_tag "file://#{Rails.root.join('public', 'images', img).to_s.gsub("/", "\\")}}", options
    end
  end
end
