Selecting different size the product image disappeared

[george90]

Hi,

I tried to use multiple combinations for my products (colors & sizes) and i faced an issue in product page.
If i choose the sizes from dropdown menu the product image disappeared and come back when i choose the color.
It seems to return an error in javascript jqzoom unable to load the image.
You can play with the test product in the below link:
