Thumbnail errors


I have the latest version of CS-Cart installed, but there are still some strange things with the thumbnails going on. (eventhough the helpdesk assisted on it, but seems to only have fix 50% of it…)

The following:

When i go through my sidebar menu to view products all thumbnails show just fine, nothing wrong there… As soon as i go through the tag cloud to a product list page, all thumbs seem to be gone, and all show NO_IMAGE.GIF.

anyone any ideas?
