Does Caffee Model work on images downloaded from google search? - neural-network

Question

So, I started with this article https://towardsdatascience.com/predict-age-and-gender-using-convolutional-neural-network-and-opencv-fd90390e3ce6 for age and gender detection and, I am facing a trivial problem. I am not able to run caffe on pictures downloaded from google. Actually, it's running only on the pictures that I take from my phone or webcam. Is there any specific reason or am I doing something incorrectly? Also I wrapping all of this with flask.
for example:- when I feed this image that i took from google search https://www.hanselman.com/blog/content/binary/WindowsLiveWriter/DIYMakingaWideAngleWebcam_1478B/2010-02-16%2023-01-29.283_2.jpg
I get this as my logs:-

As you can see i am getting 200 for pictures from webcam vs 500 for google pictures. It's not an issue with flask wrapper, rather I tested the code directly with a picture on my disk into cv.imread(), the Caffe model is not picking it up.
