Hi Roger,

from pages or articles?

If from Pages - just choose your own image.

Read tip #16 from: https://www.joomshaper.com/documentation/sp-page-builder/sp-page-builder-3/backend-editor

Hi Paul,

Thanks for your reply. I cannot see the specific instruction for what I want to do. I just want to put a link to my homepage in a Facebook post and for it to either preview the page or for me to choose an default image?

Roger, just read the last tip from guide link, starting from that part

That image "Open Graph Image" is used for Social Media, mostly Facebook, Twitter maybe more.

So just put there offer as banner image. Then after link share in FB - that new image should be used.
