If your blog is brand new and you haven’t added images to your blog yet then you can skip this step.
However, if you are an established blogger and have many images/posts on your blog then you may need to follow these steps.
Take a look at your blog and see if your images look right. Are they stretched out? Gotten small?
If they are then you’ll need to install and run the plugin called “Regenerate Thumbnails“.
Why? Every blog design is different and the widths of the post areas will be different sizes. The blog design you were using before may have had a smaller/wider post area.
1. Go do your WordPress dashboard and click on Plugins.
Next click on “Add New” at the top then type in Regenerate Thumbnails in the search area. Install it then activate it.
2. Next, go to “Tools” then click on “Regen. Thumbnails”. This is where you can run it. If you have a lot of images then it may take a while for the plugin do its magic.
