Add a photo&video gallery to my BigCommerce site

Hi Experts, Only bid if you have experience with BigCommerce. Please make sure to let me know what gallery software you intend to use when bidding. I would like to add a photo&video gallery to my BigCommerce site. A simple gallery with 4 thumbnails across and 10 down. Multiple pages. Multiple categories... When a thumbnail is clicked the image is enlarged using a lightbox. If you can add facebook commenting to each image that would be a big plus (let me know if this is possible when bidding). It must be easy to upload pictures and videos, ideally multiple users should be able to do this. Look forward to working with you!
