Thank you for your response Justin.
I do not know how to edit or cropped images. To make my work easy for me, can you help me to find a theme which can size it automatically to all the same size. I took me a long time to find a right theme, moreover I just don’t have the time to keep in sourcing for the right theme. Maybe you help me to find one suitable theme that I do not have to do any major adjustment to the image size.
