Images not rendering in PDF

[hyphen81]

This works when rendering the view in the browser, but gives me the broken image icon when I generate a PDF:

<img src="{{ public_path('images/my-image.png') }}" alt="" style="max-height:3rem;">

I've tried hard-coding the path, I've tried using asset() instead of public path (which works when rendering in the browser) I've tried using jpg or svg as an alternative, all with the same result.

in case anyone else runs into this, the answer was to base64 encode the image:

            $imagePath = public_path('images/my-image.png');
            $imageType = pathinfo($imagePath, PATHINFO_EXTENSION);
            $imageData = file_get_contents($imagePath);
            $data['base64'] = 'data:image/' . $imageType . ';base64,' . base64_encode($imageData);

and then in my blade file:

			<img src="{{ $data['base64'] }}" alt="" style="max-height:3rem;">

I can confirm that this works. I'm just curious as to why images render locally, but need (at least sometimes) base64 encoding on the server.
