Image cannot be loaded. Make sure the path is correct and images exits.

I have loaded PFDs into my media library using my Mac. Linked it to the following page -http://www.cadianetworks.com/about-us/press-releases/cadia-press-release-ops-5332a/#prettyPhoto

Using Avada Theme. I can see this PDF through Safari on my Mac but on no other browser.

I’ve tried loading PDF images from different Windows based PC and get a loading error: HTTP error.

Please advise how to correct this problem. My host suggests using something different than lightbox for loading PDFs but this does sound right.

PDF files arent images

They are and they aren’t. How else to you load PDFs into wordpress?
