To my knowledge, no. If they were erased from the memory cards while in the camera. If the memory card was downloaded to your computer, the erased pictures can be retrieved, I believe..but, someone with a lot of computer savvy needs to retrieve them...but first look in the trash ben to see if they went there. If in the trash bin, you can retrieve them from there.
Some, and possibly all, Lexar memory cards come with a bonus, Image Rescue 4, available for download. Kingston has a similar download available, Media Recover. Sandisk also has similar software. Check their web sites for more info. I'm almost certain that the software works with any brand or type of card.
