Body

The system has a built in thumbnail generator which is able to create a thumbnail image of any page or email.


The thumbnail generator is used in the following places:

  • Home Page
    • For email campaigns this shows a thumbnail of the last email that was sent
    • For websites this shows the last published version of the home page
    • For print materials this shows the last published version of page 1
  • Select/Save Layout
    • A thumbnail is shown for each layout
    • Clicking "recreate thumbnail" will regenerate the thumbnail for any layout that is not displaying correctly
  • E-Card Wizard
    • When using the e-card wizard a thumbnail of each e-card is shown on the first screen of the wizard after logging in
    • When setting up the e-card wizard and setting the Content Type of the an email to Wizard, the thumbnail will be displayed on the Email Options Metadata screen.
    • The thumbnail can be regenerated by clicking "regenerate thumbnail" on this screen

Troubleshooting Thumbnails

If thumbnails are not being generated for any page then check the following:
  • Ensure the email or page does not have any invalid HTML by checking it in the W3C validator - https://validator.w3.org/
  • Recycle the back and front-end of the application and regenerate the thumbnails. This can be done by Vuture Support from "Admin.Tasks.Recycled Vx Front-End" and "Admin.Tasks.Recycled Vx Back-End" - note that you should avoid recycling the back-end while email sends are in progress as they can get interrupted.
  • Try accessing the URL over HTTP and check it forwards correctly to HTTPS. If not then the bindings should be checked.

Thumbnail Generator Version 2

There is a new version of the thumbnail generator that has improved performance and will generate thumbnails even if there is invalid HTML on the page, which can often be the case for email templates. It is now the default for all client instances. For Vuture Administrator reference the setting is "Admin.System.Versions.Thumbnail Generator Version".
