Dear Ben, Thank you for your video. I had already figured out it btw thru your comment (it turns out it's easy in fact, and I just had to know using it on what). But I hope it will make it easy for the other people who also will look for it, and I hope they will also thank you for your help like I do. I still use the code you gave btw (so far its only issue is .png format), and I can't explain how much of helpful to me. It really helped me a lot.
