Replace picture on web object fails

When we were using Studio 13, we were able to use Web Objects and Change Picture to enable us to launch Adobe Captivate simulations of software our staff need to learn.

Now we have bought Storyline 3, I have found we have the same issue as this post. 

Unfortunately, the Captivate simulation is launched by an index.html file within a folder of published content and your workaround doesn't seem to work for it. 

It seems this is because instead of it being Open URL/file, it is now called Jump to, which just goes to the location in the folder and therefore doesn't launch the simulation.  And if I try Play Media as a trigger it of course is only looking for media files and this isn't a movie.

Any ideas, please?

I don't want to use an autolaunch, as I find them rather clumsy.

Otherwise, if we want a slide of intro text, it seems we will have to either :

• double up the slides in course or
• add a slide to every Captivate which means republishing them all too

I was hoping for a quick conversion from Studio to Storyline.

Thanks.
