With a selectmenu you can change the color of a picture.
But when the page loads, the picture has the same color as the background because it's a transparant png. I change the bgcolor instead of the picture.

The color only appears when choosing one in the menu.
I want that the picture already has a color when page loads.
I guess it's a adjusting of the code, but how ?
