A system and method are provided for conducting an electronic meeting by broadcasting a screen image to a third party computing device (desktop, laptop, tablet or smartphone) without requiring the attendee to download specialized software. The image is viewed through a standard web browser. In operation, a user is provided with a hosting account on a server, and a host computing device is loaded with a software application for communicating with the server. The user invites one or more remote viewers who connect to the server using the browser on their device. The hosting application captures image frames to be shared and divides them into subsections, transmitting to the server only those sections that have changed relative to the previously transmitted frame. The meeting attendee's browser retrieves tiles from the server as they change, and displays them for the attendee.
