How to Add Featured Images to Your Blog Posts

Featured images are essential for making your blog posts more visually appealing and shareable on social media platforms like LinkedIn, Twitter, and Facebook. Here’s how to add them to your blog posts.

What Are Featured Images?

Featured images are the main images that represent your blog posts. They appear:

• When sharing the post on social media
• In blog post listings
• As Open Graph images for better social media previews
• At the top of the blog post (optional)

Adding Featured Images to Your Posts

To add a featured image to your blog post, simply add the featuredImage object to your frontmatter:

---
title: "Your Blog Post Title"
description: "Your blog post description"
publishDate: 2024-01-15
tags: ["tag1", "tag2"]
featuredImage:
  url: "https://example.com/your-image.jpg"
  alt: "Descriptive alt text for accessibility"
  caption: "Optional caption for the image"
---

Image Requirements

For best results with social media sharing:

• Dimensions: 1200x630 pixels (1.91:1 aspect ratio)
• Format: JPG or PNG
• Size: Keep under 1MB for fast loading
• Quality: High quality but optimized for web

Image Sources

You can use images from various sources:

1. Unsplash (free): https://unsplash.com/
2. Pexels (free): https://pexels.com/
3. Your own images: Host them in your /public folder
4. Stock photo services: Getty Images, Shutterstock, etc.

Best Practices

1. Choose relevant images: The image should relate to your content
2. Use high-quality images: Blurry or pixelated images hurt your brand
3. Optimize for loading: Compress images to reduce file size
4. Write descriptive alt text: Important for accessibility and SEO
5. Test social sharing: Check how your image appears when shared

Technical Implementation

The blog system automatically:

• Generates proper Open Graph meta tags
• Creates Twitter Card meta tags
• Handles image URL validation
• Provides fallback to default blog image
• Displays the image in the blog post header

Fallback Behavior

If you don’t specify a featured image, the system will use the default blog image (/blog-og-image.png) for social media sharing.

Example Implementation

Here’s a complete example of a blog post with a featured image:

---
title: "10 Tips for Better Test Automation"
description: "Practical tips to improve your test automation strategy and reduce maintenance overhead."
publishDate: 2024-01-15
tags: ["automation", "testing", "tips"]
featuredImage:
  url: "https://images.unsplash.com/photo-1516321318423-f06f85e504b3?ixlib=rb-4.0.3&auto=format&fit=crop&w=1200&h=630&q=80"
  alt: "Computer screen showing automated test results"
  caption: "Effective test automation strategies for modern development"
