Sorry, but RoboHelp does not offer a method to achieve this. Unfortunately that's a huge hint that Adobe isn't using RoboHelp to develop those pages.
One way you might achieve it with a single image would be to insert the image *TWICE* on the page. Then scale one pretty small. Take the full sized image and tuck it inside a Dynamic HTML drop-down. The net effect would be that the user would click to see the full sized image (revealing the DHTML drop-down) and the smaller version would be "pushed" farther down the page.
Interesting. It would explain why I've been unable to achieve so many of the stylistic effects they use in their Help system. What do you think they use to create that Help then?
Thanks for the ideas. Not sure I want to fiddle too much with code that someone else surely can't maintain later. But the DHTML effect does sound like a pretty simple workaround.
Yeah, I'm unsure exactly WHAT editing software they use. Might be something internal. A quick glance at the page source mentions "LiveDocs" but that may just be some obscure internal reference.
We have been after them for a long while to eat their own dog food and use RoboHelp to maintain the help!
