How To Stop WordPress From Creating New Image Sizes

WordPress is becoming very popular day by day. WordPress provides a very user-friendly system that allows beginners to build websites very easily.

Even though WordPress is very user-friendly but it does have some problems. One of the biggest problems of using WordPress is managing the files. WordPress creates many files while operating.

Every time you upload a picture to your website, it creates some resized pictures to feed the header, featured image, homepage thumb and recommended stories. Besides that, it even creates three resized photos when you upload a picture.

As a result, uploading a single image may generate more resized images. It may sound innocent, but it will make a huge number of images on your server. Ever wondered how to stop the WordPress theme from creating regenerated images in different sizes?

The matter of great sorrow is that these images will become obsolete once you use a different theme. A new theme will require different types of image resolutions which the previously generated images won’t match. This will cause several numbers of unused and unnecessary files on the server.

Even if you generate new images for the site then you will see a huge number of obsoleted images on your server. You can always manually remove the unnecessary image files but that’s a pain that we don’t want to take.
