Abstract: A method, system, and computer program product for quickly and easily displaying and editing documents, such as advertisements. A set of master documents of advertising materials is provided, and a set of read-only documents is also provided, wherein the read-only documents are accessible from a network site by a browsing program operable on the user's computer. Preferably, each read-only document is a copy of a respective master document, and is associated with a graphical tool or editing program for editing the respective master document. The browsing program is launched and a first read-only document is accessed across the network and displayed in the browsing program. If the user selects the read-only document for editing, the corresponding master document is transferred from the network site to the user's computer system. The user may then launch a graphical tool or editing program capable of reading the master document.
