ABSTRACT:
A method and apparatus are provided for transmitting images from a first processing system to a second processing system over a communication link during a multimedia teleconference. In response to a user input at the first processing system requesting transmission of the image, a communication device in the first processing system is queried for the current bandwidth of the communication link. The communication device returns an indication of the current bandwidth, and in response to the indication, a subset of an image file is selected. The subset corresponds to one of multiple possible levels of resolution of the image. The selected subset of the image file is then transmitted to the second processing system over the communication link, such that the second processing system can display the image at full size, but at a resolution less than the full resolution if necessary, given the current bandwidth.
