To much time between photos

Hi, there are usually two reasons for this, either the battery or memory card.

Try a fresh set of alkaline batteries as they have a higher voltage than rechargeable ones.
If you notice an improvement then look on eBay for a set of Lithium Ion batteries which are rechargeable but also have a higher voltage than the NiMh cells that are usually used.

The other factor is the speed of the memory card, newer cards & higher quality cards can be written to faster, check your local camera shop & they may advise or even let you try other types.

Lastly look at the quality settings, if you're just taking snaps to email do you really need the highest quality setting? Try setting a lower quality that writes less data to the card.

Please update the question & let us know if the information given was useful to you - Good Luck!
