I think what you want to do is skew the images:
How you skew your image to make it appear foreshortened depends on your program.
If you're using Inkscape, click the "Object" menu's "Transform" command, then click the "Skew" tab. Type in numbers roughly between 5 and 15 for the "Vertical" and "Horizontal" text boxes to specify the skew angle, then click "Apply." The image you loaded will display the skewed effect.
If you're using GIMP, click the tool palette icon shaped like a trapezoid to run the "Shear" tool, then drag on the image to skew it.
For Photoshop, click the "Edit" menu's "Free transform" command, then right click your image. Click the "Skew" or "Perspective" commands, then drag the handles on the bounding box surrounding the image to preform
the skew.
For paint.net, select zoom and rotate in the layers drop down menu.
I quickly did this one in paint.net
