Can you get viruses from JPEG images?

Is accepting JPEG files from people you don't know safe? What kind of viruses/malware etc can be sent with a JPEG image?
Update: dell 8600 said that a virus can be renamed to a jpeg and then executes when opened, but a jpeg is not generally an executable filetype. So how does this work?
Update 2: Someone mentioned using a binder to bind a JPEG with a virus that executes itself when you open the JPEG. Is this actually the case? You can receive a JPEG binded with a virus and you only ever see the JPEG?
