[Tutor] PIL and converting an image to and from a string value

[Chris Hare]

What I did:

self.imageBuffer = StringIO.StringIO()
image = Image.open(filename)
image = image.resize((150,150),Image.ANTIALIAS)
image.save(self.imageBuffer, format= 'PNG')
self.imageBuffer.seek(0)
image = Image.open(self.imageBuffer)

So, that is how I got around the problem

My understanding from the reading I have done is that I have to convert the image data into a string , which I can then store in the database.  Additionally, I need to be able to take the stored image data and convert it back to an image  so I can display it in a canvas widget.  I am using the python imaging library
