As others pointed out, losing your camera is always a risk, and with it, you might lose your pictures. A couple of really easy tips:
Take a picture of your name and address. Anyone who finds your camera might turn it on, see the picture, and return the camera. You might even add "$50 reward to the person who returns this camera to me" (or whatever it is worth to you).
Put a sticker with your name and address on the inside of your camera bag. Nobody sees it until you lose your camera.
Back up your pictures. I have the Camera Kit for my iPad - it means I can (a) back up my pictures (to the Cloud when I have free internet), (b) enjoy my pictures on the large screen without needing my computer. There may be other mechanisms that work for you, depending on the toys you have.
One caveat. I had a friend who had about $8k of camera gear. He went to Spain. It was a hot day, and he was in a rental car. The window of the car was open, and the camera bag was on the seat next to him. When he stopped at a traffic light, someone reached in and grabbed the bag. Bye bye expensive camera, and all the pictures in it. It happens.
So - play it safe. Make sure the camera can find its way home, back up the pictures frequently. Also - have a spare battery / charger / memory stick. Sweden is beautiful - you don't want to run out of battery or memory just when the perfect photo opportunity presents itself!
