I just connect the camera to the laptop and download the photos in to a folder on there and delete the ones that aren't distinguishable 'thing' iykwim! Have you tried that? My DC's cameras are also at least a couple of years old though too so i don't know if they've changed them since then?
My DS got a vtech kidizoom camera for Christmas and has been enjoying using it. I have tried to delete some photos from it to free up some room, as you can imagine the sort of photos a 3 year old takes! But everytime I try to do this by pressing the X button when the photo is on the screen, it just takes me back to the main menu. Is there any way to remedy this without losing the photos from Christmas morning on it. My DD also has one that she got 3 years ago and she hasn't had any problems with it. We no longer have the receipt for it unfortunately. Any ideas anyone?
