Paste your item in the first row. You can ignore the second row. If you have more than one item to replace, as if you had a title, and text, you can use the extra columns. You can also click the add image option to add a column. Click on any row, and choose photos from your folders. Then, you can replace the background image without dragging and dropping in the steps ahead. You may need to add a frame in the background from elements.
