I've been shown some photos that seem to be distorted in such a way that there's an unnatural curve either going through the middle of the pic, or else a sort of "bending" effect. The photographer claims that this is natural -- happened when the picture was snapped, and was not digitally manipulated. Any thoughts?

Sure. As mentioned, a trick lens will do it. You can also print the picture on a stretchable medium and stretch it. This sort of thing, along with retouches, flopping of the negative, trick cropping, and other 'doctoring' techniques have been perfected since photography was invented around 1840. Digital techniques for photo trickery are only the latest.
Historically, the Hearst tabloid newspapers and the Soviet Union were the most famous photo tricksters, but they are legion.

Yes, it's called barrel distortion and pincushion distortion. They both are a result of the lens being zoomed either in or out. A normal lens will make an image that is similar to what you would see looking with your eyes. As you zoom in, the lens magnifies the center of the image and it bulges in the middle producing barrel distortion. When you zoom out from normal, the lens captures more light from the sides, compressing the center of the image, producing pincushion distortion. Sometimes this is what the photographer wants, but most of the time it's considered a flaw. Some lenses are better than others at reducing these effects. If you don't have a camera with interchangeable lenses all you can do is to not zoom out or in as much.

Not really. That's the nature of digital images. While you can shrink a photo down and have it still be crisp, you can only scale up by a small amount before it looks crappy. If you think about it, your image has a certain number of pixels per inch. That's your resolution. When you scale up, you still have the same number of pixels to work with. They just get bigger. Some software can try to interpret that sizing as best it can, but for an image to retain the same quality as the smaller original, you need more pixel information added, which can't been done.
