No teaser thumbnail, no records in teaserthumbnail table

Hi

The module is installed fine, and I followed instructions to set default options and content type options. But no teaser thumbnail image shows, and no records created in teaserthumbnail table.

Before I installed the module, the (big) image showed in the teaser. This no longer happens, so the module is doing part of its job.

Imagecache is working fine for user profiles and views etc.

I have tried editing the blog post and resubmitting.
