1. In a system that displays an image on a local display unit and on a remote display unit, which local and remote display units are used and observed by a respective local user and remote user, a method of identifying portions of the displayed images, comprising the steps of:displaying on the local unit a first local icon at a location on the locally displayed image, which location being selected by the local user; and transmitting the remote user information for generating on the remotely displayed image a first remote icon corresponding to the first local icon such that the first remote icon is displayed on the remotely displayed image at the location on the image selected by the local user; and displaying on the local unit a second local icon at a location on the locally displayed image, which location being selected by the remote user; and providing the first remote icon with an appearance indicating that the location of the first remote icon was selected by the local user and not the remote user. 2. The method of claim 1 further comprising the steps of:providing both the local and remote units with means to change the size of the remotely and locally displayed images by zooming; and including in the information transmitted to the remote user data representing the size of the displayed local image thereby to permit the first remote icon to be displayed on the remote image at the location selected by the local user irrespective of differences in the size of the image displayed on the remote and the local units. 3. The method of claim 1 further comprising the steps of:providing both the local and remote units with means to display selected portions of the remote and local images by panning; and including in the information transmitted to the remote user data representing the location of the first local icon relative to a portion of the image that is common to both the local and remote image thereby to permit the first remote icon to be displayed on the remote image at the location selected by the local user irrespective of differences in the portions of the images selected for display on the remote and the local units. 4. The method of claim 1 further comprising the steps of:providing both the local and remote units with means to display two or more images at a time and for selecting one of the two or more images on which to display a first local icon; and including in the information transmitted to the remote user data representing the one of the displayed two or more images on which the first local icon is displayed. 5. The method of claim 1 further comprising the steps of:providing means for displaying on the local and remote units text information for display with the displayed image; including in the information transmitted to the remote user data representing text information for display; and associating the text information with the first local icon, thereby to associate that text information with the first remote icon. 6. The method of claim 1 further comprising in addition to the displaying and transmitting steps the step of removing from the local unit the displayed first local icon; andtransmitting to the remote user information for removing the first remote icon from the remotely displayed image. 7. The method of claim 6 further comprising the step of providing on the local unit a touch screen for permitting the local user to touch the local unit for removing from the local unit the displayed first local icon.8. The method of claim 7 further comprising the step of displaying on the local unit a virtual button that when touched by the local user is identified as a command for removing from local unit the displayed first local icon.9. The method of claim 1 including the steps of:linking the local and remote units via a telecommunications system; and sending voice data simultaneously with the information for generating the first remote icon. 10. The method of claim 1 including the step of packaging the local unit as a portable device connectable with more than one type of telecommunications system.11. The method of claim 1 including the step of storing on the remote unit information representative of the remotely displayed image and first remote icon, thereby to enable later display of that image with the first remote icon.12. The method of claim 1 further comprising the step of providing on the local unit a touch screen for permitting the local user to touch the local unit for selecting the location of the first local icon.13. The method of claim 12 further comprising the step of displaying on the local unit a virtual button that, once touched, identifies a subsequent touch of the touch screen by the local user as the location selected for the local icon.14. In a system that displays an image on a local display unit and on a remote display unit, which local and remote display units are used and observed by a respective local user and remote user, a method of identifying portions of the displayed images, comprising the steps of:generating at the remote unit an image; displaying the image on the remote unit; transmitting the image to the local unit for display on the local unit; on the local unit, pointing a first local icon to a location on the locally displayed image, which location being selected by the local user; transmitting to the remote user information for generating on the remotely displayed image a first remote icon corresponding to the first local icon such that the first remote icon is displayed on the remotely displayed image at the location on the image selected by the local user and on the local unit simultaneously with the pointing of the first icon, pointing a second local icon to a location on the locally displayed image, which location being selected by the remote user. 15. The method of claim 14 including the step of assigning to the second local icon an appearance unlike that of the first local icon.
