ABSTRAKFotografi memegang peranan yang cukup penting dalam mensukseskan kegiatan promosi sebuah institusi sekolah di media sosial. SMA Kristen Imanuel Batam memiliki website dan media sosial namun foto yang ditampilkan dinilai sangat minim dalam menginformasikan kepada masyarakat tentang sekolah dan kegiatannya. Foto yang digunakan sudah bersifat overused dan tidak memiliki daya tarik dikarenakan tidak melalui proses editing. Oleh karena itu, perlu dilakukan photostock untuk memperbarui koleksi foto. Proses pelaksanaan kegiatan photostock menggunakan metode 4D yang terdiri dari define, design, develop dan disseminate. Kegiatan photostock telah membantu SMA Kristen Immanuel memperoleh stok foto sejumlah 100 foto sebagai informasi sekolah yang ditampilkan melalui instagram dan upaya promosi bagi masyarakat di Kota Batam khususnya bagi calon murid baru supaya lebih mengenal sekolah, kegiatan pembelajaran dan prestasi yang telah diraih.
