Memory cards often start at 2GB in size. The amount of photos/videos you can take depends on the megapixel setting on your camera but generally an 8GB card will allow you to take hundreds. Videos take up more space than still photos.
We always recommend you back up your images regularly in batches of up to 500, eg: after a holiday or Christmas. This prevents loss of data on your memory card. You could use CDs, USB drives or external hard drives to then store them permanently. Then you can delete the pictures off your memory card and start again! Formatting your memory card deletes the pictures and also gives it a ‘clean’. Simply hitting delete does not. So always format your cards to minimise the risk of any data corruption.
