I’ve go this page laid out as a Single Author, small preview pic (no author picture display, feature image is small). The preview image size is auto based on column or layout width.
For some reason, some of the small preview pics are appearing with a gray background, and others are appearing cropped. When I looked into the individual posts, the image sizes were the same.
Hey!
It’s because some images have a different aspect ratio so instead of cropping them to 180×180 it does 180×120, you could add this to Quick CSS to make sure all images look square:
.blog-meta img.attachment-square.size-square {
min-width: 80px;
min-height: 80px;
}
Alternatively you could this plugin to specifically set the size of the images:
