make 2 rectangles 100 mm width and  200 mm hight

 and 100 x 150 mm

choose a design and drag the image into CorelDRAW

Right click on the image to edit it

Adjust the settings to remove the background and to show the details of the image

Make a rectangle that is tangent to the stand body and choose the "virtual segment delete" tool

Cut the tangent line

Make sure the rectangle is half the width of stand body; in my case I draw a 50 mm width and 6 mm hight
