Apple Imac Hard drive failed--Apple TV question?

My Mac recently crashed and since it is more than 6 years old .. Apple said it is "Vintage". We had pics on the Mac from last 6 months that were not backed up. However we do have a 1st Generation Apple TV that I have synced pics to. Are those pics available even though the Mac is not working? If so how do I share those pics from Apple TV back to a new IMac? Anyone have a good solution for picture storage if this was to happen again? maybe Picasso? THANKS!
