color image to black and white when clicked on- Captivate 9

If you are happy without the rollover state it works with multistate image. If you want the rollover state to change to black&white and clicking to have that B&W state to remain permanent, also when returning to the slide you need an image converted to a shape button as the first user replied. Moreover you'll have to add a custom 4th state, which is a duplicate of either the down or the rollover state, I will label that state 'Done'. The Success event of the shape button will then need to trigger an action that has or includes the command:

   Change state of ShapeButton to Done

​I prefer this scenario because you need only one object instead of two (image + click box).

Do not forget to check the option 'Retain state' in both this and Steve's scenario! That will preserve the Done state when returning to the slide.

Here are some links to posts that could help:

I do that all the time Anastaisum

Hello!  Are you sure it's actually an image?  My guess is it could be a smart shape using an image as a fill.  I'm going to answer as if that was the case.  If it's not, maybe you'd reply with more details or screenshots to help narrow down what's going on.

Smart Shapes in Captivate 9 can act as buttons, and have 'states' (normal, rollover and down).  It could be that it's a smart shape with an image fill, and the rollover and down states have been set to be a different color than the 'normal'.

Here's how to check.  Select the item.  Look in the upper right under Properties.  If it says 'SmartShape_somenumber', then you know it's a SmartShape.  If someone changed the name, another way to check is to look under the Fill area.  You can see in my screenshot below that you can see a (stretched out) version of the image on the screen.  That's the image fill the SmartShape is using.

If it indeed is a SmartShape, you can click the 'State View' button and see the normal, rollover and down states. 

Once you're in State view, that will tell you at a glance if the rollover and down states are set to be gray!  You could click on the Fill button to check how it's been edited.

The below image is what you see when you click on the Fill button.  Click on the little blue pencil to see the color options.  Those options are where it could have been set to grayscale.

Hope that helps!
