ZEN lightbox extra information on images

Is it possible to add extra line for info to the product image if Im using zen lightbox
It would be useful for me to specify a color for example if the product is viewed.
an example what im lookin for
http://www.oomipood.ee/product/tr103.102os/karaokevoimendi-kajaga-2-50w-display

If clicked on the image there is a gray line below with extra information available for the product.
Is it possible to create one on zen also?

as there is a 7 minute editing limit I would like to put it like this to be more clear

Is it possible to add extra line for info to the products each image if Im using zen lightbox
I concidered adding it to the image name if I could display one in lightbox
It would be useful for me to specify a model (a white sandal picture will have a line below saying "white" or if its not possible any other way "1076_white.jpg" ) for example if the specific image is viewed. On the other image "pink" and so one. This is quite obvious example but it would be useful if the models are white/blue and blue/white so the customer can also figure out what is what.
