On most of SheShoppes themes, featured images or post thumbnails appear above or next to the post’s excerpt. Homepage slider, Recent Posts widget, Popular Posts widget, Related Posts thumbnails and many other of our features also use the posts’ featured images or post thumbnails.
How to add a featured image or post thumbnail
Go to your post editor.
Click the Settings icon and click the Document tab.
Scroll down and click the Featured Image tab.
Click the Set Featured Image button, and upload your post thumbnail or you can pick an existing image for your Image Gallery.
Save the post.
Tips: Using a plugin to manage your featured images
I love using Quick Featured Images plugin to manage my Featured Images. It helps me change and assign my post thumbnails quickly and easily.
