So you are on MAC...
Questions

1) have you try to run our Examples related to pictures:
        API_way/..Pictures
        SQL_way/..Pictures


2) Valentina stored in BLOB picture as JPG.
    BLOB field have method as
      WriteTodisk() which upload to disk location  BLOB contents as is,
      so you can use this as easy workaround to extract back JPG.


3) Does Valentina Studio can open your db and show your pictures correctly?


Answer this please and we decide next step.
