MarketPress - Product Variation Bug

Hello!

The product variation option is not working correctly on my client's website. When you view the product in the product category [http://rosesjewelrybox.com/store/products/category/bracelets] you can click the 'choose options' button. Instead of going directly to the page, it shows a popup (which is fine) but it does not switch through the different images that correspond with the individual product colors. [see attached]

However, if you are on the product page itself [http://rosesjewelrybox.com/store/products/emma/], there are no issues other than the images appear blurry for no reason. Not sure why this is happening either. Can you please help me with this issue?

Thank you!
