HyperThumbnail for EPiServer

Have you ever seen sites that show thumbnails of the target pages when you hover over hyperlinks? Ever wished that your EPiServer site could do that too? HyperThumbnail is a very quick and easy way to add thumbnail functionality to your EPiServer site. Just drag-and-drop two files into your EPiServer site folder and take it for a spin.

The module will automatically add a thumbnail to all the hyperlinks in your EPiServer HTML content. To do this it will find all LongString-based EPiServer properties on your pages and search for hyperlinks. If it finds any then it will check to see if it already has any kind of mouseover/mouseout function and, if not, add a thumbnail to that link.


  • Pop-ups with DHTML
  • No AJAX
  • Compatible with many browsers (IE/FireFox/Safari)
  • Thumbnail caching (client and server)
  • Can be easily retro-fitted to an existing site

  • Using the EPiServer plugin attributes for storing settings
  • Implementing CSS classes
  • Making the thumbnail frame configurable
  • Configurable Cache length
