[Plugin: POST2PDF Converter] Not retrieving featured image

I’m excited to have discovered your plugin, and so far am very pleased with the ease of use. There is one issue that I am encountering though, in that PDFs converted from single posts fail to display any image(s).

My theme (WP Navigator) uses TimThumb to insert featured and other attached images in a gallery div, independent of the post entry. Here’s a link to the demo for reference: https://themes.themolitor.com/wpnavigator/2011/07/eiffel-tower/.

Do you have any suggestions on how to retrieve the featured image so it will display on the PDF?

PS – my site is a client portal with sensitive information, so I am unable to provide a direct link, and I am using the Simple Access Control plugin to restrict access to logged-in users only.

Thanks in advance for any assistance you can provide!
