Chevereto doesn't use the chv_images.image_delete_hash column at all since v3.0.0 and when you update from 2.X to 3.X that column gets removed. It impossible that you install Chevereto 3 with that column present in the database.
That's why I asked to provide details. I know the system backwards and I know that there is something odd here. That column must not be there, simple as that.
I don't have any clue on why you have that colum there, the only thing I can suggest you is to try to stick to my database schema.
