I think it's a pretty poor thing to do. If you don't have a camera, say so and use a manufacturer's picture, identifying it as such. If the product is unopened, then do the same thing. If a person wants to use another person's picture, he could have the courtesy to ask.
And here's another point, what if somebody thinks your picture is the one lifted from the other person and thinks you're the one who is being deceitful? I'd like this practice to be discouraged by the forum administrators when pointed out to them, unless it's a manufacturer's photo.
On a related point, I had an ad not too long ago. A few days after the ad expired, there was a new listing for the same product. I had a look at it out of curiosity. The guy used his own pictures but he cut and pasted my description of the product! I didn't know what to think. On the one hand I thought it was flattering he liked my description. On the other hand, you feel like the person is somewhat underhanded. It makes you wonder what else the person would do. Certainly not anyone I would trust to deal with.
