Adobe Captivate 8 create a toggle between show/hide image

Have several examples on my blog. But here we go:

1. Create a user variable v_visib with a default value of 0
2. Create a conditional advanced action for the button like this:

     IF v_visib is equal to 0

           Show image

           Toggle v_visib

     ELSE

           Hide image

           Toggle v_visib

BTW since you are on CP8, don't use an advanced but a shared action. The only parameter will be the image. You can then use that action over and over again, even in other projects. For another project: open the Library of this older project in the new project, drag the Shared action to the library of the new project. The variable v_visib will be automatically created, and when using that shared action, you'll just have to define the parameter (image), or you can even replace the image by another object or by a group.

You can feel that I like shared actions, not everyone agrees with me however.

Have a look at my blog, have several posts about shared actions, this is the last one: Reuse Shared Actions in other Projects - Captivate 7 vs. 8 - Captivate blog
