    QDataWidgetMapper does the link between widgets and database fields.

    How are you storing images in that database ?

          sorry for late xD 600 second cooldown
          @SGaist u mean by fixed is that a single format ? like png or jpg ?
          if so no it wwill be just one format
          and its controlable by the user

          *its a desktop app that is controlable by just one user so the format type is not an issue

            Will you use a QTableView ? If so you can either use a custom QIdentityProxyModel that will create a QPixmap from the blob for the DecorationRole or a custom QStyledItemDelegate to draw the blob.

                It depends on how you want your user to access the data.

                    This looks like a classic web application.

                    While you can do the front end with Qt, I think you should first rethink your backend architecture to provide all the services needed to manage such an application.
