Computers A very old camera, a few questions. Any help?

Hi,
I was looking in my house, as you do and I came across a very old camera:

The Kodak Instamatic 233

I understand that it is about 30 years old I think. It takes a Kodak 126 film, huge buggers. Well The questions I have are:

I cant find where the hell you put the damn battery, It appears that there is nowhere to insert one?

Also I think there is a film in it, I took a look, but its sort of strange, theres no photo strip thingy, it seems to be empty but its definatly a film. Anyone know what that is?

Flash cubes? Where do you put them and can you buy them anymore?

This is a great little camera, I think its more for a professional user. I do have a photo that came from this camera, it looks like those old photos with the white border and a bigger part of white at the bottom. But the quality is amazing for such an old camera.

Any help is much appreciated, I dont know wether this is meant to be in this forum, but I diddnt know where else to put it.
