Expand Your Mind - Puzzles and Brain Teasers

The code that most of those books show you though is very limited and needs to be modified significantly if it is to be incorporated into pages where there are other scripts in use. The slideshow script that the examples on this page use is significantly different from most of those scripts. Another way in which this script is different is that it is completely unobtrusive (as all JavaScript these days should be) and only needs a div tag in the page with a recognisable id in order for it to know where to display the slideshow. HeartPrevious Next The array is an array of objects rather than an array of images because this script not only displays the images but it displays a caption under each image as well. If you want to add image slideshows like this to your site then the first thing you need to do is to obtain the script.
