camera for kids

Try putting the card from the camera that won't upload into the other camera, and upload from that; or use a card reader instead of uploading direct from the camera. Good luck!

There are different settings on your camera that let you set the size of the picture in resolution. The bigger the resolution, the bigger the picture and more space it takes for the pictures. Check your manual and learn how to set the resolution to get the number on the card that the manufacturer says you can. 20 pictures were probably taken at the highest resolution. The higher the resolution also the plainer the picture. As for the problem with uploading the pictures from one camera, I have no idea what to tell you about that.

the quantity of pictures that can be store on memory card depends on memory size vs. the picture quality. for ex. if you select picture quality 1024*768 and memory size is x and if you can store 10 pic. then with picture quality 640*256 you can store 15-20 pic. on same card.

okay this is kinda funny, but I have almost the same camera, and when i go it i could only take 20 aswell, you need to buy a micro sd card. But make sure you look in the manual as some sizes may be too big.
