hello to everyone.
First of all thanks a lot for reading this post and being able to help.
I have a while where in each iteration I take a photo.
I have a boolean variable which toggle with a few consideration.
I would like to visualize an image just if that boolean variable is true, but if it is false I would like to visualize the image of last iteration. I mean if boolean variable is true, refresh the image but if it is false do not refresh.
I do a case but if the variable is false then the image display does not visualize anything...
So how can I do that?
thanks a lot

I tried that option, but the problem is that I have the image of the last iteration but not the right image...
