Just to explain ...
I know that taking a picture is not complicated issue with uniGUI. By the way, it's quite simple. But everyday people ask me how to do it. So I posted this example for a quick way to answer everyone.
Soon I will also put examples how-to do sound and video also.
So, don't criticize me for such a silly example. Some are still learning and need help. I'm instructor and teacher.
Education, training, writing are my expertise.
