wxPanel question

[Anand]

Hi Pythons

   I am writing a small program to store pictures as thumbnailed
albums using
wxPython. 
  
  For this I have a wxPanel containing a number of thumbnailed
bitmaps(of type
wxStaticBitmap). Is there a way I can save the contents of the entire
panel to one  image file. Does wxPanel support streaming ? If it does
I guess I should be able to convert the stream to a wxImage.

Many thanks,

Anand
