Hardcoded cover.png

[salim-b]

In latest seo/opengraph.html partial the image file path assets/cover.png is hardcoded. This results in the following warnings if the file doesn't exist:

WARN  [Hugo SEO] Missing default image for og:image - assets/cover.png does not exist. Use a high-quality image with dimensions of at least 1200 x 630 pixels, while keeping the file size under 8 MB.
WARN  [Hugo SEO] Missing default image for og:image - Add 'images: ['cover.png']' to your hugo.yaml

Why would you instruct the user to set images: ['cover.png'] in their hugo.yaml when cover.png is hardcoded in the partial? And why would you hardcode the image file path in the first place?

Also I have a hard time to understand the purpose of the the first 11 lines:

Maybe you could shed some light on this @h-enk ? Thanks!

I agree that there's room for improvement — to be picked up in a next round

Dropped the lines w/ v2.2.0 — now fully in line w/ Hugo's template (no warning if a user forgot to add an image)

Maybe re-adding it at a later date, but making it flexible — like how it's done with favicons
