Submitted by: Johnny Sim-Bravenboer


This macro is a combination of the Auto Reload function (which is part of K-Meleon 0.9) and the Link Increment macro.

When looking at a picture on a webpage that has pictures that are named in sequence, (pic01.jpg, pic02.jpg, pic03.jpg, etc...)
this macro will create an instant slideshow and automatically go to the next picture in sequence.

To stop the slideshow, click on the "back" button.

As this is a Javascript program, there is a limited functionality while watching the slideshow, for example;

  • K-Meleon will stop functioning properly when going to full screen when the slideshow is running, so you will need to restart K-Meleon.
  • The only way to stop the slideshow is the "back" button or to close the tab/window.
  • Before the slideshow starts, the user needs to enter a time for the interval between pictures loading.
  • The counter will not wait for a picture to load before it goes on to the next, so you will need to set a longer time on slow web-pages.
  • The Address Bar will not be properly updated during the slideshow.

This is not a full featured macro, but it does the job ;-)

Note: You might like to use the Auto Image Resize macro, to enable automatic picture resizing, or add this macro to
the Image Browsing Toolbar, as I did.
