Hello @BarbaraU ,
To get two blocks to be beside each other in a single row, you'll need to drag one of the blocks to the others' sides - either to the left or right edge depending on how you want to place it. You should see a pink line indicating where the block will be dropped when you let go of it. You can also use a layout that has an image beside a text block automatically.
