Change Variation Images on the list

Hi Guys,

thanks for the awesome plugin. I just have one issue:

1) My colors are images
2) I want to display ONLY the colors on the list pages
3) I switched the “color” setting in the globale attributes on.

But now when I click on a swatch on the list page, the variation image change to the image of the color.

I need to display the image of the color as a swatch and by clicking this swatch the variation image has to change (not displaying the swatch image (because its only a color))

Thanks for your help
