I have had a kind advice from a member saying that the image I posted here is too large.
Please let me make an excuse for my own small honor.
I uploaded my image from my PC first but it was evidently too large to view comfortably. So I deleted.
Then, I transferred the same image to another server on the net so that I can make a link between the server and this thread. In this case, the image cannot look too large first unless a reader click to enlarge.
Minimizing the size using a software is one way but I wanted to post it in the original size because other readers who are interested in the parts may want to evaluate it in full size.
Above was all of my processings for a post.
Thank you for your advice and understanding.
