I haven't used this, but I have used a number of other applications that work like this. Basically, giving 'display' the option '-immutable' and throwing it into the background makes display sorta kinda act like a server of sorts -- commands can be given to it. Which is where '-remote' comes in -- it's saying to 'display' to look for an already running instance of 'display' and then to change the image being used. Mozilla has similar operations that can be used to reload/load a new page in an existing window, or to use an already running process to open a new window/tab. (For the OP - had you considered loading the image in Mozilla/Galeon/Opera/Phoenix... and setting an autoreload on it, either via the tab/window preferences or using mozilla-remote?) -- Matthew Weier O'Phinney [EMAIL PROTECTED] http://matthew.weierophinney.net -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
