Abstract
Abstract A method of facilitating electronic presentations using portable storage media. An array of images to be displayed to an audience is converted into a database and stored on the presenter's computer hard drive. A copy of the image database is transferred to a portable storage medium, such as a personal computer (PC) card, which is then inserted into a display device such as a liquid crystal display (LCD) panel equipped to accept a PC card. When the presenter selects which image is to be displayed to the audience, the selection is communicated to the LCD panel which displays the corresponding image in the database copy on the PC card for viewing by the audience. The present invention also includes a system for giving electronic presentations.
