How add png image to zip file using std.zip?

[Marcone via Digitalmars-d-learn]

        ZipArchive zip = new ZipArchive();
        std.file.write("foo.zip", zip.build());
        ArchiveMember f = new ArchiveMember();
        f.name = "Wallpaper_001.png";
        
        zip.addMember(f);
        std.file.write("foo.zip", zip.build());

File is added with file size 0.
How can I use expandedData for add images files? Or what I use 
for it?
