on GAE i use: def download(): ...do stuff return img.execute_transforms(images.JPEG)
where the google image object (img) returns a binary stream as a result of execute_transforms. if you return just binary data from a controller function in web2py, web2py does nothing more to the return, it just streams it to the user. hope that helps. cfh On Jun 13, 10:20 pm, Jason Brower <[email protected]> wrote: > Yeah I like that approach.
