If a file has actually been "overwritten" and not just "deleted" then no your photos are toast. Had they been deleted you may of had a chance. However you might want to attempt to use a program such as Tenorshare Data Recovery and try and recover your pictures. I doubt it will find anything that is actually recoverable but it never hurts to try.
