This is a direct download of a free program that might do what you want. It is extremely good at recovering normally deleted/corrupt/formatted pics which might otherwise be lost forever. Not guaranteed but certainly worth a try.
Before running the program, create a new Folder on your Desktop, give it a name and then from within the program you can Browse to that folder where you should find your recovered pics, provided it works for you of course. You can cancel the process at any time, any pics recovered up to that point will still be in your created folder. You can even open your created folder and see the recovered pics appearing. Make sure you choose the drive letter given to your card.
A useful little program to keep on your PC/Laptop.
