To add slides to a slideshow, create a <slide> element for each slide in the slideshow source file:
<slideshow>
<!-- first slide -->
<slide>
</slide>
<!-- second slide -->
<slide>
</slide>
</slideshow>
To describe each slide, add the elements that describe it:
<slideshow>
<slide>
<!-- the image to display in the first slide -->
<image url='images/plant0.jpg' />
</slide>
<slide>
<!-- the image to display in the second slide -->
<image url='images/plant1.jpg' />
</slide>
</slideshow>
