Designing certificates with the current editor is...”challenging”. This is one of the ideas that needs upvoting:

https://community.docebo.com/ideas/certificate-design-show-background-image-1613One idea you can try in the meantime is to use an old-style HTML editor (NVU is one idea) that can display your background image while you do the layout over the top of the image with something like tables (yes...so 20th century!). Then you’ll need to tweak the code a bit with the Docebo built-in editor.
In our company we use different types of certificates for different types of courses, but here’s a generic ILT template we use (horizontal orientation):
