Is there a way to freeze an image for a few seconds?
In case that I have found a result, I'd like to freeze a live image for a few seconds (or even only an overlay).
The timer module seems to do exactly the opposite, performing everything from begin up to the timer module, until a ceratin wait time has passed.

Yes, you can use a combination of Marker modules to achieve that.
See attached. This will freeze the image when a lot of red stuff is seen.

STeven,
Sorry, but your program does not freeze anything here. And yes, I checked the value of the variable, it is large enough.
For me it seems that even in the case that the if loop is entered, the next program loop starts again with a live image.
I can obviously use a simple time.sleep(5) command in a python subscript, as attached, so there is an easy workaround.

Thomas,
Sorry for the confusion ... the above robofile will freeze on the last large red item. So while there is a lot of red the image will update in realtime. When there isn't enough red it will just show the last image that did have enough red.
While your robofile works, you will notice that the app appears to freeze entirely during that time ... this includes opening files, saving, etc. since you are freezing the pipeline everything is synced to that pipeline which can cause other issues. If that's not a concern you are good to go.
I've included an updated robofile that doesn't cause this app freeze.
