You need to save the PhotoImage as a class variable so the reference can stay in memory. The following method for image() should work:

def image(self):
    self.logo = Tkinter.PhotoImage(file="linux.gif")
    w1 = Tkinter.Label(self, image=self.logo)
    w1.grid(column=5,row=7)

This page provides a more in-depth explanation: Effbot PhotoImage. Specifically this section:

Note: When a PhotoImage object is garbage-collected by Python (e.g. when you return from a function which stored an image in a local variable), the image is cleared even if it’s being displayed by a Tkinter widget.
