In the past, we have covered the Methods to Set a Default Fallback Image for WordPress Post Thumbnails and in this article, we will see how you can regenerate the thumbnail image sizes on your WordPress site. So let’s have a brief look:-
An Overview of WordPress Thumbnail Images
When you upload an image to your WordPress website By default, it automatically creates various sized images and saves them for later use. The default setting for your WordPress thumbnails is 150px by 150px which is a square. You can select from the Medium default size which is 600px by 600px and the Large which is 1024px by 1024px. These image dimensions are needed for showing images perfectly on your website indifferent to their actual size. These sizes can be changed by navigating to Settings > Media.
The main problem is modifying your Media settings does not always work when it comes to the accurate display of images on your site. While changing themes your images will save in newly defined dimensions and sizes different than your original theme sizes.
Unluckily these new image sizes only apply to images uploaded after activating your new theme. This means any old images you have saved in your WordPress database will remain inaccurately sized and display distorted on the front-end of your Website.
For solving this problem you must regenerate new sizes for all previously uploaded images.
