# show a jpeg (.jpg) image using wxPython, newer coding style
two different ways to load and display are given

app = wx.PySimpleApp()
create a window/frame, no parent, -1 is default ID
increase the size of the frame for larger images
frame1 = wx.Frame(None, -1, "An image on a panel", size = (400, 300))
call the derived class
Panel1(frame1,-1)
frame1.Show(1)
app.MainLoop()</pre>
