A slide magazine has a base portion and partitioning walls which project upwardly away from the base portion at mutual spacings to form compartments for accommodating respective slide frames. The partitioning walls are of a height which is adapted to the slide frames and at their ends remote from the base portion are connected together by a strip-shaped holding portion extending over the length of the slide magazine so each compartment can be loaded and unloaded from both sides. To prevent the slide frame in a compartment from falling out laterally, provided at each side of each compartment is at least one resilient retaining portion in the form of a resilient finger with a retaining nose arranged to engage the slide frame.
