Product Page Image Size

Hi i’m having an issue with the size of the product image within the single-product view.

After activating the plugin the size of the product image, also the thumbs have been resized to a smaller size, so they aren’t filling the left div as it was before.

Here is a screenshot of my problem.

I am running bootstrap version 3.x @4cols per row, if i switch to v2.x the single product page is fine, but the shop page shows only one product per row.

Please help.
Regards.
