What version of InDesign are you using? How did you export the Interactive PDF (exact steps)?
1. 'm using CS5 (trial)
2. It is one page and I've used for multiple state options. When I select the buttons only the new button appears, so the state does not change. In order to show the rear view image I've selected to use a roll over. But when roll over it does not work. In the preview everything works fine.I'm testing indesign to see if the features support my needs, exporting to swf is not an option. It must work without flash.
3. I export to Adobe PDF (interactive)

Embed page thumbnails
Layout single page
Open in full screen mode
Page transitions none
Buttons and media Include all
Compression Jpeg 2000
Multiple State options don't work in an Interactive PDF file. They only work with Flash (SWF) export.
To create buttons that show and hide, you need to create buttons with show/hide options.
To learn how to create Show/Hide buttons, do a Google search on "Show Hide button InDesign" or use InDesign Help.
Actually I was using 5.5 trial. Does that make a difference?
This PDF was actually meant to be much more expanded and it took me a lot of time to figure out this way, but I assume that it is hardly possible to show many different images from front and back. Or is it worth a try?
It makes no difference whether you're using the trial or not. Don't try to use the Multistate Object feature because it's not supported in PDF. Learn to create Show/Hide buttons to do the same thing.
If you create a multistate object, export as a swf, reimport that swf into your InDesign comp, then export as an interactive PDF...the multistate object works.
At least it does with all the ones I've created. Are there exceptions?
Yes, you can do that, but you lose a lot of control because it's just a workaround. You get more control to use Show/Hide buttons directly with the PDF. For example, you can test and adjust using the Preview panel.
Ahh, of course.
Say, has there been any talk about adding more interactivity like image sequencing to PDFs?
The problem is that PDF is no longer under Adobe's control. It's an ISO standard. Changing ISO standards is always a slow process so don't hold your breath.
