By default, wally stores images in $HOME/Pictures/wally.

The Init method is called on initiation and returns number of available images to download. Then for each image Fetch is called and the result is stored at the user specific location. By implementing this interface you can create new sources for wally.

For adding new source you only need to create a new sub-command in cmd package and then calling your new source with provided path. Also for saving images you can use the following helper function:

func (u *Unsplash) Store(name string, content io.ReadCloser) {
        path := path.Join(
                u.Path,
                fmt.Sprintf("%s-%s.jpg", u.Prefix, name),
        )

        if _, err := os.Stat(path); err == nil {
                pterm.Warning.Printf("%s is already exists\n", path)

                return
        }

        file, err := os.Create(path)
        if err != nil {
                pterm.Error.Printf("os.Create: %v\n", err)

                return
        }

        bytes, err := io.Copy(file, content)
        if err != nil {
                pterm.Error.Printf("io.Copy (%d bytes): %v\n", bytes, err)
        }

        if err := file.Close(); err != nil {
                pterm.Error.Printf("(*os.File).Close: %v", err)
        }

        if err := content.Close(); err != nil {
                pterm.Error.Printf("(*io.ReadCloser).Close: %v", err)
        }
}
