Dragging Images to the Canvas
Any photo or upload can be dragged and dropped onto the canvas as a “Background” or “Resizable” image by dragging it onto a particular “zone” on the canvas.
This is just one way of adding an image, you can of course always click a thumbnail and then “Convert to resizable image” if you want to have more refined control of it.
You can also drag an image from your computer anywhere on the canvas to have it instantly start uploading!
