This question sounds easy, but it is not as simple as it sounds.
Brief summary of what\'s wrong
For an example, use this board; http://pinterest
Probably a bit late but, with py3-pinterest open source project you can do it easily:
First get all pins as objects from the board, they include the original image url also.
# get all pins for the board
board_pins = []
pin_batch = pinterest.board_feed(board_id=target_board['id'], board_url=target_board['url'])
while len(pin_batch) > 0:
board_pins += pin_batch
pin_batch = pinterest.board_feed(board_id=target_board['id'], board_url=target_board['url'])
Then you can obtain the image urls and download them or do whatever you like with them
for pin in board_pins:
url = pin['image']
# process image url..

Yes its python but if you still insist on c# it should be easy to port it :)
