when you open a new project, a blank timeline and a blank bin with one gallery will be opened. the blank gallery will be named gallery.gy. the .gy extension is used by dpsvelocity to identify the file as a gallery file.

    whenever you save a gallery, the .gy extension will be automatically added to the gallery name.

    you can rename a gallery by right clicking on it and choosing rename gallery, or by going to the main menu and choosing file ] gallery ] rename.
