OpenCV can't open certain jpg files:

import cv2

img = cv2.imread('/absolute_path/sun_afmzwxkzmxkbamqi.jpg',0)

img is None # True

works absolutely fine here. what's your os ? opencv version ? did you build from src ?

try a print cv2.getBuildInformation() , what does the ' Media I/O:' section look like ?

I think opencv cannot load gif image and your image is in GIF format

@LBerger, why do you think, it's a gif ?

^^ hmm, i see. so just copying the img link to this site must have made a conversion...

i guess, it's better to remove it again ?
