Sometimes changing your WordPress theme makes featured images and thumbnails to be displayed very poorly. Have you encountered this problem? don’t worry. In this article, we will teach you how to regenerate thumbnails in WordPress.
How to regenerate thumbnails in WordPress?
When you change your WordPress template, there is a possibility that your featured images won’t display properly and they may display in a different size than what your site requires.
The reason behind this is, many WordPress themes have different sizes for featured images. This makes your previous featured images useless in the new environment. Therefore, you must regenerate your thumbnails.
By default, featured images are 150px*150px. You can also select the medium size which is 600px*600px. There is also a bigger size for featured images which is 1024px*1024px.
Regardless of the size of your images, such standards are needed to display images correctly in WordPress.
These sizes are also customizable. To do so you head over to “Settings” and then “Media”. The size you set will be used for the new images that you upload on your website. The previous images will remain the same.
Therefore, it’s important to quickly regenerate your thumbnails when you face this problem. The most efficient and easy way to do so is by using the Regenerate Thumbnails plugin.
