Otherwise, we need the web address of that directory. To determine that address:
<ol><li>Please visit a node on the site containing images, or a user profile with an uploaded picture. Try to find an example where the full resolution image is displayed.</li>
<li>Right-click on the picture and look for an operation such as <em>View Image</em>.</li>
<li>Choose that function and look at the URL of the image - it will usually look something like <em>http://example.com/sites/default/files/pictures/picture-3.jpg</em> (for user pictures) or <em>http://example.com/sites/default/files/my-photo.jpg</em> (for files uploaded to nodes).</li>
<li>If you see after the <em>files</em> portion of the path something like <em>styles</em> or <em>imagecache</em>, you are most likely looking at an automatically generated variation of the image, not the original. It will take some trial and error, removing intermediate portions of the path (such as <em>styles/medium/</em>) to find the original image.</li>
<li>Please enter the full address of the files directory (<em>http://example.com/sites/default/files/</em>) below. Leave the field empty to skip migrating files.</li></ol>'),
