Focus Point: Smarter Image Cropping
Other galleries crops all images from the center. If the subject is off-center, it may be cropped out. WordPress Gallery Extra‘s Focus Point feature allows you to tag the subject in an image and ensures it is not lost during cropping.
You can use fixed aspect ratio without having to worry about stretching your pictures or cropping out the main focus of the image. All images will automatically crop, on the fly, to meet your design’s needs.
