Lightbox with social share button

Hey Rikard!
Thanks for your answer – I have a gallery with pictures. And when I click on one of the pictures I want it to be opened in a lightbox. In the lightbox I want to have the following infos: 1. Name of the image, 2. a number like 3/99 (number 3 of 99 pictures) and 3. a button “share with facebook” with the possibility to post this picture on my site and – most important to share this picture as a private facebook-message to a friend. and perhaps 4. a button to share this picture via email.
The provided link shows a page with a gallery of pictures (in the end it should be 99 posters/pictures). For these 99 pictures I need a lightbox with the features mentiones above.
I tried to do this with a post/blog-gallery which i put below the first gallery – this works somehow but I dont think this is the smartest way to show the pictures WITH the wanted social-share-possibility.
I hope I explained my problem properly.
Would be cool, hearing from you!
