Hello,
When we use image type message as output parameter, it is clickable, therefore can be enlarged, etc.
But when we use it in a combo together with a button, it is not clickable and cannot be enlarged.
How we can make them work together? We want such image to be clickable, user to enlarge it, see it, and when ready, to click on a button “Continue” so they can proceed further with the flow.
Thanks! 
Hi. You are right, images in combos don’t get enlarged when clicked. Actually, images in combos are there just to attract the user’s attention as opposed to the images displayed independently, which the user should be able to view. We will, however, add it to our enhancement list to be implemented in the future. If you wish, you can even create your own fork of TWC with the functionality you need. Its source code is publically available here and its API is described here.
