But, what if I want to use already uploaded image file, not images
from DB??
This code produces BadImageError:
img_path = os.path.join(os.path.abspath(os.path.dirname
(__file__)), 'img_folder', 'img_file_name')
img_blob = db.Blob(open(img_path).read())
img = images.Image(img_blob)
img.resize(width=80, height=100)
img.im_feeling_lucky()
thumbnail = img.execute_transforms()
