Yo Yo Sushi

I am going to Yo Yo Sushi again for lunch to meet Maria, my friend from high school. We go there a lot since we can get the food from the sushi boat fast and then leave to go back to work. Last night, I had dinner at In&Out Burger, it is so much better than McDonald's. My dad and my uncle like eating at In&Out Burger. I started playing with my digital camera last night and each picture was about 1MegaByte big, and I set the camera for 5.2 Mega pixels. Is there a way I can decrease the memory size to KiloByte for each picture?
