Ill be looking into the documentation asap. In the meantime, you can simply use the
slideshowpopupconfig.ini as a pointer to the settings for using the popup slideshow. The only main difference, is that the following parameter is enabled:
...which allows the Slideshow to run a javascript that resizes the window appropriately for every new image. Elsewise, you will simply need a javascript that opens the popup window like in our example:
javascript:window.open('https://www.photo.gallery/imagevue/slideshow.php?
configfile=slideshowpopupconfig.ini','popslideshow',
'width=400,height=250,toolbar=0,location=0,directories=0,
status=0,menubar=0,scrollbars=0,resizable=0,top='
+Math.round(screen.height/2-125)+',left='+Math.round(screen.width/2-200)+'');void(0);
