Automation of Google and Yelp posting pictures

Hi there! I'm looking for an automation to post pictures on Yelp, Google, Instagram, Twitter and other sites at the same time. Currently my business takes pictures of customers through a phone. From there, we manually upload to each and every site, which we ALL KNOW is tiresome and not money efficient. We have used tools like OneUpApp, but would like to include Yelp into the system. Any tips please, or better yet, how would you do this?
