title: One question survey app Google Apps Script and Google Sheets with user management
body: <p>I have to do a little bit of "crowdsourcing" for my work and it would consist in a very simple web app where a user can register/log in, and then be taken to a page where a picture is shown to a user and submit a number.</p>
  
  <p>I'd like to be able to set up a few rules to choose which picture the user will see (so he won't have to answer twice the same question and also to allow some overlap between users to compare their answers).</p>
  
  <p>We can assume that I have a google sheet with a list of images URLs that can be accessed and that I would like the answers to be populated there.</p>
  
  <p>I figured that this tutorial would be a good start since it handles user creation and management and user can submit ideas : </p>

  <p>That being said I'm a bit clueless, I've tried to look for sample scripts deployed as web app but it's hard to know where to start.</p>
  
  <p>I'll appreciate any help !</p>
