Types of Images Used in Blog Posts
Most WordPress articles use:
Featured Images
The main image associated with the article.
Featured images often appear:

Images placed within the body of your article.
These help explain concepts and improve readability.

Step 1: Prepare Your Image
Before uploading:
✅ Choose a relevant image
✅ Resize when necessary
✅ Use a descriptive filename
Good filename:
Plain Text

Avoid:

Search engines can use filenames to understand image content.
Step 2: Open Your WordPress Post
From the WordPress Dashboard:
Posts → All Posts
Select an existing article or create a new one.
Place your cursor where you’d like the image to appear.
Step 3: Add an Image Block
Click the:
+
button in the editor.
Search for:
Image
Select the Image block.
You can then:
- Upload a file
- Choose from the Media Library
- Insert from a URL
Uploading directly from your computer is usually easiest.
Step 4: Upload Your Image
Select your file and upload it.
WordPress will automatically store it in your Media Library.
Once uploaded, the image will appear inside your post.
Step 5: Add Alt Text
Alt text helps:
- Search engines understand the image
- Improve accessibility
- Assist screen readers
Example:

Not every image requires a caption, but they can add context when helpful.
