Yea you do get points for photo blogs but they aren’t enough if the pictures are not really good and high resolution.
Instead try writing short write ups with the pictures about the place in it or your experience, and this will help you earn more credits like around 70.
There are 2 things to keep in mind 1. great photos in terms of quality and should speak volumes for the place in itself.
2. A small description along with the picture to give a brief idea of the place.
The photo blogs may give you around 45 credits. You can check my profile for photo blog ideas .
Yes you will... but make sure the photos aren't copied from somewhere, write some good captions, do not upload same image, upload more number of photos from the trip, and let it be like a real story... All the best
