So I create a jpg in gimp and save it.
If I email this to a windowz user they cannot open it unless I name it something.jpg

Why does windows need these extensions when Linux seems to know what the files are allready?

It's because of backward compatibility, mostly. Windows is based on DOS, where extensions were important. Just a different design philosophy...
Plus, in Linux there's 'file' command. Even when you don't give a picture an extension, when you run 'file imagename' you'll be told which picture format it is. It makes writing programs chooseing the right method to deal with a file easier.
