Invoice images [7.7.4]

The images on the invoices are missing from the PDFs
They do appear in the templates though…

These images are our logos so need to be rectified ASAP - we can’t invoice!

It also appears that Quotes are also effected… :¬/

No problem with permissions it seems (no problem opening the images when copying the URL from the template).
Was working under previous version (7.6.x I think)…

Anyone confirm this or have any ideas please…?
Images are not showing up on ANY PDFs at all…

Github issue created:

Looks like a bug with PDFs and PNGs
Changing the image type to a JPG and use that instead and the images appear properly.
