I would like to insert an image (in ligth grays) created with PsTricks (similar to the popular TikZ) as a background image in moderncv. In the PsTricks images I would insert some LaTeX formulas in light gray in the background.
An alternative option were put some images in some particular positions as ligth gray backgrounds.
How could we do that?
