Many times, digital cameras do not have sufficient memory space. It is true that the in-built memory can vary depending on the brand of digital camera. In a few cases, the in-built memory can store just about 15 numbers of pictures. Your kids may get it not enough while going out in a break. For this reason, it would be great, if you could get bigger the default memory space. This can offer your kid flexibility to accumulate a larger number of pictures.
