Hello,

I want to know how can i crop an existent image in gcs and save it?

until now, i have achieved to crop the image by using 

img = images.Image(filename=obj_fileinfo.gs_object_name)
img.crop(0.0, 0.0, (200.0 / 300.0), (150.0 / 300.0))
img.im_feeling_lucky()
thumbnail = img.execute_transforms(output_encoding=images.JPEG)

and serve the image 

self.response.headers['Content-Type'] = 'image/jpeg'
self.response.out.write(thumbnail)

but, I need to create an url to serve the image already cropped. I suppose 
that i need to save the cropped image in GCS and create it a serving url, 
but i don't know how can i do this. 

Can someone help me, please?
