title: How to display images in rows and columns?
body: <p>I am querying some images from database and displaying them on the webpage. However, I would like to display these images in rows and columns as thumbnails. </p>
  
  <p>For example:</p>
  
  <p>If c1, c2, c3, c4 and c5 are 5 columns and r1, r2, and r3 are 3 rows, then the page should show 15 image thumbnails. </p>
  
  <p>I'm using bootstrap. </p>
  
  <p>Thanks in advance for any help.</p>
