Picture formatting on mobile

We are trying to find the best setup to show image headers properly here

On desktop all looks good, only on mobile the option on “Section 4” adding a formula with Image() works fine.

Any hints how the column needs to be formatted?

Are you wanting to show an image header for the page or are you looking to show images full width for each row of a table?

The options for a full page header are above the section title if you hover there on desktop, you’ll see an “Options” button to click.

For a table, on desktop, you can change the table to a card layout, then use the card layout settings to choose the image URL column and set the image to be “top”. Then you can change it back to a table, and it should stay for mobile.
