How do I link to an image so that it opens the asset with the Cascade interface?

I have a non-published page that provides content for two published pages, and also defines a thumbnail that is used by a page outside the CMS. I'd like to be able to get to the thumbnail from the non-published page to publish it, but my links only open the image itself, not within the Cascade interface. I have access to the name and path of the image from the page's data definition, but not the ID.

   Hi Dave,

   Assuming that you can attach a Velocity format to a region of your non-published page, you can use the LocatorTool to find the ID string of an image. Here is an example of using a Velocity format to create two links:
   

   #set( $image = "/images/howto/2-column-config.jpg" )
   #set( $site  = "cascade-admin" )
   #set( $file  = $_.locateFile( $image, $site ) )
   #set( $id    = $file.identifier.id )
   <ul>
   <li><a href="http://yourdomain.edu:1234/entity/edit.act?id=$id&amp;type=file" target="_blank">Edit the file</a></li>
   <li><a href="http://yourdomain.edu:1234/entity/publish.act?id=$id&amp;type=file" target="_blank">Publish the file</a></li>
   </ul>
   

   There are a few things worth mentioning:

   1. Given an ID string, you can use any valid URL inside Cascade to open, edit, or publish an asset.
      
   2. Note that the ampersand must be encoded, or else Velocity will throw an exception.
      
   3. I use target here. This will open a new tab or window. This is to avoid embedding a window inside Cascade.
      
   4. The file path can be from a data definition block, an index block, or whatever source. You may need to process a link element to get the site name.

   By clicking one of these links, I can either edit or publish the image.

   Thanks Wing! I wasn't using Velocity on this page, and wasn't familiar with the available tools, so double thanks!

   Surely you can do this using XSLT, provided you know how to query the database directly with an XSLT format. I may talk about that in the conference next year.
