Click link on web based slide show to xatshow website?

I have a web based slide show with over 300 pictures. It works great.
How do I remove the click link to the xatshow website if someone
clicks on the actual picture. I am evaluating the software right now
however I do not want people to click and go to some other website. I
want them to stay on my website and prefer to take away the hyperlink
on the picture!! If I register my software will this be removed or is
this the way it is?
