title: Android request images from web server with user criteria
body: <p>What is the correct technique used to request images from a web server according to a user selected criteria?</p>
  
  <p>I am referring to a shop-like application where, for example, the user selects to see "t-shirt AND size M AND black color". I assume the web server is organized with a database with picture names and categories and a separate folder to store pictures (which I do not know if is the correct approach to the situation).</p>
