You can paste a PICT image from the clipboard. This is the Mac OS standard
image format; most graphics are placed in the clipboard in PICT format. Images
from web browsers, illustration packages, image editing tools, CAD programs,
and digital camera images can all be brought into CU-SeeMe's Slide Window.
For example, to easily get graphics from the web into the slide window, you can copy an image
from your web browser. This converts the GIF or JPEG file into PICT for the clipboard.
If you click and hold the mouse down on an image in Netscape, you get a popup menu like
the one below.
Of course, be sure to respect copyright laws.
