Go to a store that has the machine where you can order a CD of your pictures rather than getting prints. Walgreens, Walmart, etc...

Its a good idea to buy a card reader for your type of card so you dont have to use up battery power while uploading photos to your computer. It saves a lot in batteries.

As for your battery, if you have rechargeables, you should always keep spares and only recharge when battery completely dies, dont charge just because you used it, only when it dies....this will prolong the life of your battery/batteries.
