No, but be careful anyway.
Well...yes, technically, it is possible, but only under the following scenario. Your computer has to already be infected with another virus whose purpose is to act as interpreter for the image virus. Seems kind of pointless to me. (The "Perrun Virus" was an example of this kind of virus, which attached to jpg files. A lot of hype, not much action)
However, you still need to be careful when opening images attached to emails. Be sure that the file extension really is an image extension (the ones you listed, plus a few others). I've seen emails come in with file names like "yourpicture.jpg.exe". Clever. The extension isn't really 'jpg', it's 'exe', and you already know you should never open those.
And remember: if the attachment is from someone you don't know, why would you bother opening it anyway?
