The copyright photos can be purchased either in print form or digital form. Printed photos are cheaper than digital photos. But printed photos need to be picked up (in person) while the digital form can be downloaded. More details on access to photos from Perpustakaan Foto.
Payment is required before the photos can be picked up or downloaded.
If Jabatan Penerangan Malaysia photos are used for any type of publication, the author/editor must deposit a copy of his/her published book/material at the department.
I don't know what the English name of the department is. Maybe, Department of Public Information Malaysia?
