Thumbnails

Hi I want to ask. When we customise the product for example a shirt has sleeves and torso etc. and we customise the colours accordingly but when customising that the plugin doesn't show thumbnails for the part. We can add the name but not the picture for that part to show the thumbnail. Can we do that in some way? Or If I pay you can you customise the plugin? And what will be the charges kindly let me know as soon as possible
