The 8GB should be for mass memory card instead of photo internal memory. To recover data from it, you can rely on a third-party Nokia mass memory card recovery software (see resource). Also remember - not to put anything back to the card in case the data overwritten.
It depends on the type of nokia phone that you have. Most nokia phones has a microSD card slot so you can add more memory to your phone.
