For older blogs that have a tremendous amount of posts and images, the change in thumbnail size can create a huge problem for all the featured images and inserted images that come with every post.
Whenever you upload an image onto the Media Library, WordPress immediately creates resized versions of that image, based on the registered image sizes on your site. This includes the values from Media Settings and from anything registered by the theme or plugins.
The problem occurs when there’s a sudden change in theme or featured post dimensions, making resizing and regenerating thumbnails an enormous task to accomplish. You’d have to go back and regenerate each image and thumbnail, adjust their sizes to fit your current thumbnail dimensions. Doing that for each one of your thousands of posts can be dauntingâ€”and, not to mention, time consuming.
What is Regenerate Thumbnails?
Regenerate Thumbnails is a plugin for WordPress that allows you to re-create, or regenerate the thumbnails for your image attachments. It allows you to either regenerate all your thumbnails, individual thumbnails, or just specific thumbnails for the image attachments on your WordPress site.
How to Use the Regenerate Thumbnails Plugin
Under the â€œToolsâ€ tab in your WordPress dashboard, is the Regenerate Thumbnails tab. Through here, you can choose to regenerate all the thumbnails of your images. Of course, how fast this process takes is mostly dependent on how many images it has to go through.
If you’d like to go through the list of images faster, and perhaps select only a few images that absolutely require resizing and regenerating, then you could enter the Media Library. Whenever you hover over a particular image, you’ll see that an additional option has appeared besides the usual Edit, Delete Permanently, and View options. Here you can choose to regenerate individual images, or check a number of them and them perform the bulk action of regenerating thumbnails.
Whether you see it as an advantage or not, the Regenerate Thumbnails plugin keeps all of your old thumbnailsâ€”as they might still be in use somewhere inside your blog or your blog’s coding.
All in all, Regenerate Thumbnails performs one specific function for your blog, and it does it perfectly. For any and all old blogs that are undergoing a revamp of their entire website, Regenerate Thumbnails is the perfect tool to help in managing and resizing those old images to make way for the new. The plugin is overly simple and lightweight. There are no steep learning curves, and using it can be a joy, especially when you’re thinking about giving your site a makeover.
The importance, after all, of resizing your images accordingly, to fit the design and aesthetics of your blog, cannot be stressed more. After all, images are a powerful tool in creating a connection with your audience. That’s why every blogger uses at least one image for each of their blog posts. Find the perfect image that grabs readers’ attention and at the same time encapsulates your main thought or idea, and you can guarantee that your readers will be more responsive towards your posts.
