Now you can easily find images inside your post content and change their format size. Great tool when switching to a new WordPress theme or changing the layout of your website.
When an image is uploaded to WordPress, it generates several versions of that image in different sizes. The image is then inserted in content using ADD MEDIA button in visual editor and a custom image size format is selected.
But when you switch to new theme with different content area size, your old post images starts to look odd. Sometimes they overflow to sidebars or to other elements etc.
This happens because the images you insert in your content becomes the part of your content, they are hardcoded in posts and remains the same even when you switch to a new layout.
Hence, in result your images do not fit perfectly with the new design.
