You can import images to Maestro Label Designer by clicking on "Images" in the vertical toolbar to the left of the screen, then "+Upload New Image." To add the image to your design, click on the thumbnail preview. Your image will be automatically added to your label design.
To resize your image, select it on your canvas. Find any of the white boxes around the edges and pull them in or out to create your desired size. Note: By default, your image will scale proportionally. If you want to stretch or shrink your image independent of its aspect ratio, hold down the shift key while dragging the white boxes.
