Add comments to lightbox

I need a comments box added to every large photo that is enlarged by a lightbox (fancybox) modal window. See the page here: [login to view URL] Click on any of the photos on the right to enlarge them. When they are enlarge, I need a small icon placed on the bottom-left of the photo. Similar to the social icons at the top-right. When you click this button, the photo will be pushed to the right, and a box needs to appear which has information about that one photo. If the user keeps scrolling through the photos, and the box is displaying the text - then the text needs to change for every photo. So - every photo has its own unique text. If you click the little icon, it will hide the text box, and the photo will become larger. When the photo is pushed to the right, it will need to work as if the viewport had been narrowed. Ie. - the photo will scale smaller, so you can still see the whole photo. Closing the text box will make the photo return to taking up maximum screen space. Let me know if you have any questions. I need this done in one day.
