been using the standard image field for years and when i create a node the image displays fine. when i go to my front page which i have set to display a teaser of the last 5 posts the image displays as a thumbnail in the teaser.

this module displays all the images fine in the node but there are no thumbnails in the teaser on the front page

any suggestions? thanks

front page with thumbnails from image field
