    Hey guys!

    I looked through the forums but no solution seemed to work for me, sorry!

    I have a TV for a preview image for blogposts and want to hide it if the user doesn't specify it when creating a new blogpost.

    This is my chunk:
    <div class="ditto_summaryPost">
  <img src="[[++site_url]]assets/images/[[+tv.PreviewImage]]" width="50px" height="50px" alt="[[+pagetitle]]" style="float: left; padding-right: 5px;" />
  <h3><a href="[[~[[+id]]]]" title="[[+pagetitle]]">[[+pagetitle]]</a></h3>
   
  [[+introtext:empty=`[[+content]]`]]
  <p class="ditto_link"><a href="[[~[[+id]]]]" class="readmore">Weiterlesen</a></p>
   
</div>


    TV is "PreviewImage" and this
    [[+tv.PreviewImage:isempty=``:else"<img src="[[++site_url]]assets/images/[[+tv.PreviewImage]]" width="50px" height="50px" alt="[[+pagetitle]]" style="float: left; padding-right: 5px;" />`]]

    doesn't work for me...

    Any suggestions?

    Thank you in advance!

    - Chris

      Instead of using empty you should try: isnot

      Like this:
      [[+tv.PreviewImage:isnot=``:else"<img src="[[++site_url]]assets/images/[[+tv.PreviewImage]]" width="50px" height="50px" alt="[[+pagetitle]]" style="float: left; padding-right: 5px;" />`]]

        Thanks! But this works only partially - now when I define a "PreviewImage", it only shows the filename of the image but not the image itself. Strange?!

          Sorry - I made some mistyping...

          Try this:
          [[+tv.PreviewImage:isnot=``:then=`<img src="[[++site_url]]assets/images/[[+tv.PreviewImage]]" width="50px" height="50px" alt="[[+pagetitle]]" style="float: left; padding-right: 5px;" />`]]

            That did it! Thank you very much Henrik!
