title: Multiple file extensions within the same directory using Gulp
body: <p>So I have a gulpfile.js setup.</p>
  
  <p>In an images folder I have a few images, some are pngs, some jpgs and some gifs.</p>
  
  <p>I want to target all the pngs, jpgs and gifs in the images folder.</p>
  
  <p>I could use **/* to target everything in the folder, but I don't want to, I want it to be specific to the file types.</p>
  
  <p>I could also do this and specify each file type individually:</p>
  
  <pre><code>return gulp.src('./images/*.jpg', './images/*.png', './images/*.gif')
  </code></pre>
  
  <p>But it's a lot of repeating yourself and it seems that there should be an easier way.</p>
  
  <p>I'm looking for something like this:</p>
  
  <pre><code>return gulp.src('./images/*.{png, gif, jpg}')
  </code></pre>
  
  <p>But alas, the above doesn't work (or at least it only works for the first file type in the list)</p>
  
  <p>Anyone know how to do this?</p>
  
  <p>Thanks</p>
