I use the Crop Thumbnails Plugin on pretty much every WordPress site I setup. More and more WordPress themes are becoming image heavy using a pre post image in particular. All the designs from our designer feature images on every page and most of our sites leverage the featured image feature in WordPress.
This quite often leads to cropping issues as WordPress tries its best to cut out a square int he middle.
The theme I use here makes use of Featured Images all over the place and at all sizes. For example I have the WordPress logo & word mark appear for posts that are about WordPress in general.
You can see from this that WordPress has clipped the edge off both sides of the image to get it into a 1:1 square.
With Crop Thumbnails I can draw the cropping box myself making sure not to clip anything.
There was no way to fit the whole of WordPress into the ratio of the thumbnails on this theme but I could fit the logo. In the WordPress media library this image is the same as the full word mark. There is also no wasted space in this image with the logo nearly touching every side.
You can see from the Jekyll image on this site that sometimes you can’t quite get it but with Crop Thumbnails I can at least control where the clipping happens.
You can get Crop Thumbnails from wordpress.org here.
