Images are working on my site with mPDF and domPDF.

It seems your images are not accessible for the pdf.
Do you have something like admintools running, a htaccess file etc. which may prevent access?
You don't have https.
Your site is pretty slow.

You can try to play with Fabrik PDF options (in Options/Lists).
Turn J! error reporting on. Maybe you'll get some information in the PDF file (you won't be able to open it with Acrobat but have a look with e.g. notepad++).
