Change image when selecting a color without changing the price

Hello,

I just bought your extension and everything great!
However I have a problem and to shorten the story for you I run a sticker site and when I select a color I would like it to select the image with the corresponding color. So you are going to tell me to go in the variations and to select the attribute with the image etc … Only I have 3 Attributes with all different choices. So to add an image with the right color I have to do 300 types of variations … While I just want it to select the corresponding image with the color without changing the base price.

I would have something else to ask you if this is possible in future updates: possibility to change the color of a PNG image using PHP or JavaScript.

Thanking you.
