How to adjust thumbnail images‘ scale?
My problem is I want to change the thumbnail image/featured picture’s scale. Because when it is showed in homepage, the scale for the thumbnail image is too big to show the entire picture. Therefore some very important part of image was cut. For example, I upload a picture of a speaker as the thumbnail image, but when it comes to the home page, his head was cut. I want to change the scale of thumbnail image, which part can be edited to change it?
