In my custom table I've got a column of an image field which for a newly created record is filled by a dummy file as default.
It turned out that the dummy images in the CMP table are not wanted anymore. So I emptied the image field directly in the custom table via phpAdmin.
But they are not gone in the CMP table since there the created thumbs are shown.
What have I to do in the package configuration (or elsewhere) to clear these thumbs too?
