Image Module

The Image Module allows users to upload images as nodes.

It creates duplicate content on sites—at least two duplicate URLs for every image node created.

In the image above, the link to "Thumbnail" appends the query string ?size=thumbnail to the URL and redisplays the content. Once you are on the thumbnail page, a link to the preview page will be displayed. If you have allowed anonymous users to "View Original Image" in the Access Control settings, then there will be an additional link to the original image.

The URLs of duplicate content that a default installation of the Image Module are shown below:

• http://example.com/node-title — this is the actual node's URL
• http://example.com/node-title?size=thumbnail
• http://example.com/node-title?size=preview
• http://example.com/node-title?size=_original

The names of the image sizes are controlled through the Image Module settings at http://example.com/admin/settings/image:



So, for example, if you created an additional image size called tiny, the Image Module would then create an extra page of duplicate content for each image node on the site by appending ?size=tiny to the original URLs of the nodes.

To fix this issue, add the following line to your robots.txt file:

Disallow: /*size=
