title: Format for a url that goes to Google image search?
body: <p>I have a web page which has links  at the bottom like this: </p>
  
  <pre><code>- &lt;a href='http://www.google.com/q?rome+photos'&gt;photos of rome&lt;/a&gt;
  - &lt;a href='http://www.google.com/q?paris+photos'&gt;photos of paris&lt;/a&gt;
  - &lt;a href='http://www.google.com/q?london+photos'&gt;photos of london&lt;/a&gt;
  </code></pre>
  
  <p>The idea is that if somebody clicks we go to Google search image page and we search for those images of those cities. </p>
  
  <p>The questions are:</p>
  
  <ol>
  <li>what's the right URL for starting an image search in Google </li>
  <li>is there a place in Google documentation where I can find this ? (I searched and could not find it)</li>
  <li>does Google restrict this type of usage for some reasons?</li>
  </ol>
  
  <p>Edit:
  The 3rd point is very important to me:
  it's okay to work out the url from blogs and others but the question remains:
  is google okay with this ?
  will it ever discourage this approach ?
  if so then all my urls would become suddenly worth nothing</p>
