Abstract
In accordance with one or more embodiments of the present disclosure, methods and apparatus are provided for efficient and effective loading of media in a multi-media presentation, such that a user may be able to view and/or edit the presentation. In one embodiment, a method for loading media comprises providing a maximum number of layers per page of a collage document, the collage document including at least one page having a plurality of layers, and each layer being associated with a media object. The method further includes loading a first page of the collage document to a client device, and creating a list of layers of the loaded page, with each layer indexed by at least a position in the collage document. The method continues by filtering the list of layers based on at least the position in the collage document and a visual window of a user interface to thereby display visible layers of the loaded page within the visual window. In another embodiment, a method for loading media comprises receiving a request for a collage document, receiving a specification of a maximum number of layers per page of the collage document, and returning a page of the requested collage document.
