Snipcart image issue

When using the Snipcart module any images uploaded show as an attachment. When on a product page the thumbnails are blank with the text of the image file and if you click on it the image displays as a full window without ability to go from one image to the next (like any ecommerce site). Is there a workaround or setting to allow more of a carousel function like expected? Also any ability to upload videos would be beneficial.
