Hislide is built into Xara, and very easy to use. It's what Xara uses when you add a link to an image "Popup photo".
However it does show the slide show in a frame floating above the page, which may not be what you want?
Neither does it start automatically.
I did a little test with one of those dynamicdrive scripts, Flexislide http://www.dynamicdrive.com/dynamici...flexislide.htm , and it worked very well.

It tested how it would work with transparent overlay and objects behind the slideshow, which worked flawlessly
I just copied the srcipt from the page and put it inside a HTMLplaceholder in Xara (600x400px).
Then I changed the filenames (with relative path) and put the files into an img folder located at the same place as the index.htm file.

Code:
variableslide[0]=['img/1-1-1.jpg', '', '']
variableslide[1]=['img/1-1-4.jpg', '', '']
variableslide[2]=['img/1-1-9.jpg', '', '']
variableslide[3]=['img/1-1-12.jpg', '', '']
variableslide[4]=['img/1-1-14.jpg', '', '']
variableslide[5]=['img/1-2-1.jpg', '', '']

//configure the below 3 variables to set the dimension/background color of the slideshow

var slidewidth='600px' //set to width of LARGEST image in your slideshow
var slideheight='400px' //set to height of LARGEST iamge in your slideshow, plus any text description
var slidebgcolor='#A3A3A3'

//configure the below variable to determine the delay between image rotations (in miliseconds)
var slidedelay=3000
I also changed the delay to 4sec.
And the max size to 600x400px.
When publishing I transfered that img folder manually.
But it could probably be made automatically by "hiding" the images somewhere?
