Images that represent the preview for the theme must be 16:9. Traditionally they were 4:3, but we are looking for a frontend modernization here.
To reduce the migration cost for our customers so they don't have to take screenshots at 16:9 for each of their themes we propose this solution:
- Stick the image to the top and left of the card and make the width adapt to the available space. In this way, only the bottom part of the image will be cropped. Most probably our customers will be ok with this solution.
- Our themes will have a new display image for this card at 16:9 and we expect customers to replicate what we do.
Nothing will break and we expect them to learn on the way.
