Hi!

There are two rollovers!

If you have a look to the toolbar:

4th element is the one with the blue box --- 'mini slidelet'? (Sorry, I have a
German version with other names of the tools...).

11th element is a 'rollover picture'.

If you use the 'mini slidelet' with the blue box you have to enter that
element first. THEN click into the blue box and you will get a new timeline at
the top of Captivate. It is named "timeline for mini slidelet" and if you leave
the blue box by clicking outside the blue box you get the normal "timeline of
slide xxx". So you have a new slide with its own timeline inside your big slide.

For your photo with rollover effect: enter that element 'mini slidelet'.
Click into the blue box.
Enter your photo by clicking on the 10th tool in the toolbar ('picture').
The picture is part of the timeline mini slidelet now and not part of the
normal timeline of the slide.

Additional information: on a mini slidelet you can not use click boxes,
buttons, other mini slidelets or rollovers. Would be a nice function to use
them there...

Hope you could understand my answer...
