If there's a resource you can't render from an html file, you could always try retrieving it beforehand and embedding it with something like what is shown in this comment: https://github.com/mileszs/wicked_pdf/issues/36#issuecomment-91027880

@prashant-maropost, bellow works <%= wicked_pdf_image_tag( request.ssl? ? photo["first_resize"] : photo["first_resize"].gsub("https://", "http://")) %>

@iamfree-com The original poster said that his image is forcefully redirected to HTTPS when you request over HTTP, so while your solution may work for you, it won't in this case.

@prashant-maropost I believe the issue you are describing can be solved by installing one of the more recent versions of wkhtmltopdf.

There were some versions of wkhtmltopdf (in the earlier 12.x version range) that used SSLv3 for HTTPS. Many hosts disabled SSLv3 at the router layer to prevent Heartbleed attacks, so many (but not all) HTTPs requests just kind of stopped working when they did that.

I recommend updating to the newest wkhtmltopdf version and seeing if that solves your issue. If your CentOS package repository doesn't have one new enough, try the wkhtmltopdf-binary gem.
