Lost Photo's but some video saved

Chelsey and I took a trip down the west Washington coast on January 1st. We got tons of great pictures on her new birthday camera but I somehow managed to delete them by putting them on to my Linux computer thinking I was being a tech savvy computer guy. Somehow all of the pictures went missing. I don't know how or why, but they're gone. I managed to salvage some of the videos from the camera though. Here's one of Ryker playing fetch. http://www.youtube.com/watch?v=_i5tx0BI8Ms
