Often questions are very easy to answer if the asker would search a few minutes in the internet and has the right search terms handy.

The latter one is the key, the askers often didn't know what to search for to find the right answers which often already exists many times.

Regarding to this question I want to know the all day policy here. I dont favor to copy tutorials already available in the net but post the link with some hints. Furthermore, I don't explain each mousemove and fingertip for the right approach but try to give a usefull script to implement the solution.

In the question above I already answered the solution and without any intention of the asker a power user did it again, more than half an hour later, targeting megadummies.
