a named pipe might help. you'll need to write a simple program that extracts the scanned image and writes that image to stdout. redirect that output to the named pipe. the pipe can then be opened for reading by a browser and it will read your program's output. a useful reference: http://www2.linuxjournal.com/article/2156 the trick is getting your scanning program to run at the right time. I imagine this could be done using some sort of icon on the desktop or on a toolbar. or maybe your sane driver/program can be configured to run a script sometime during the scanning process. - Ben _______________________________________________ RLUG mailing list [email protected] http://lists.rlug.org/mailman/listinfo/rlug
