[Newb] Still not able to solve class attribution

Hi folks

I still have not been able to solve this one, which didn't manage to
garner a response yesterday, so I'm rephrasing it here. 

If I define an attribute in the __init__ statement of a class, I should be
able to access that attribute in a later method of that class, right?

I have run into a situation where that does not SEEM to happen [newbie
alert]. 

What should I be looking into to try to solve this bug, as I am SOL with
new ideas?!

Although I am using wx, I do not believe that this has anything to do with
wx, but with syntax / semantics.

Any thoughts are very much appreciated.

I copy the original question below, for convenience.

class GIP(wx.Frame):
    def __init__(self, parent, ID, title):
        wx.Frame.__init__(self, parent, ID, title, size = (600, 460))

        ....

       self.Image = wx.StaticBitmap(self, -1, wx.EmptyBitmap(*self.thumbSize),
            pos = (160,10))     <<<<<<<<<<<<<<<<<<<<I thunk I dunnit here!

       ....

    def DisplayImg(self, rot):
        self.SetStatusText('Current image: ' + self.jpgList[self.curJpg])
        img = wx.Image(self.jpgList[self.curJpg], wx.BITMAP_TYPE_JPEG)
        if rot == 90:
            img = img.Rotate90()
        elif rot == 180:
            img = img.Rotate(1, (0,0))
        elif rot == 270:
            img = img.Rotate(1.5, (0,0))
        img = self.ScaleImg(img)
        img = wx.BitmapFromImage(img)
        self.Image.SetBitmap(img)      <<<<<<<<<<<<<<<<<<<<<<<Problem
