Finding a featured image for your posts shouldn’t have to be hard. Most people choose the most magnetic image in each post as the featured image. Featured Image Generator for WordPress can also help. It can search free photos from sites like unsplash and lets you import them with one click.
Featured Image Generator allows you to set default size and customize font for your featured image. You also get simple editing functions to make your images look just right. Once you have prepared your featured posts, you can save them to your Media Library.
You will be able to play around with flexible layers and move/resize objects on your featured image. The Pro version comes with unlimited layers and template manager.
