New ... Initializes and migrates relevant schemas

func (*ImgDB) AddImg

func (this *ImgDB) AddImg(name string, data []byte) (imgModel *ImageFile, err error)

AddImg ... Extracts image features as search index Save to file system then add in database Filters out images too small beyond a limit Index and logic inspired from https://tinyurl.com/yaup47bg
