##### And you can use it like this:
## Asume that profile is some model and image is an imagefield of that model
profile.image.save('some name.jpg',get_img_obj('http://google.com/logo.jpg'))#url
profile.image.save('some name.jpg',get_img_obj(relativefile='images/logo.jpg'))# the file is on ~/django_project/static/image/logo.jpg
profile.image.save('some name.jpg',get_img_obj(absolutefile='~/userfile.jpg'))# you pass the full path to the file
