title: Convert table column data type from image to varbinary
body: <p>I have a table like:</p>
  
  <pre><code>create table tbl ( 
    id int,
    data image
  )
  </code></pre>
  
  <p>It's found that the column <code>data</code> have very small size, which can be stored in <code>varbinary(200)</code></p>
  
  <p>So the new table would be,</p>
  
  <pre><code>create table tbl ( 
      id int,
      data varbinary(200)
  )
  </code></pre>
  
  <p>How can I migrate this table to new design <strong><em>without loosing the data in it.</em></strong></p>
