As to the image, that is possible. You can use the image region to display an image from a file. Just provide the filename based on the combobox selection. You also could perhaps embed the graphics in the sm file by reading them into a matrix using functions from Mathcad toolbox.
You also could dynamically generate the images using the standard plot region, X-Y plot region or modeller region.
