I doubt, if it has been wiped, that it is recoverable. When a hard drive is 'wiped' or 'deleted',the info is still there, but the 'tags' that tell the system where to find it are removed. That is why it is relatively simple to recover info from drives. Memory cards are different. If it is, and they usually are, ram, then the info, once gone is gone forever. You could, if you haven't alredy try 'googling'. It can take a lot of searching through unrlated sites, but if the photo's are worth it, give it a go.
