Thanks everyone for your responses to this. When I got home, I called the photo studio where I got my camera and he told me that once I deleted them, that was it, they were gone. Well I then called Canon and was told the same thing. I suggested to the representative from Canon that they needed to change the "do you want to reformat" to "do you want to delete" for those of us who are computer or electronically stupid. So I thought that I would never be able to get it together. Luckily, we had been to SeaWorld before so I just used those pictures for my scrapbook. The sad part was losing the family pictures and those with my daughter and the characters. However, anytime Disney took pictures, or SeaWorld, we had purchased those. So it's not an entire loss.
Again thenk you for your responses. It's so nice to know that there are still caring people out there.
