Using Default/Fallback Images Effectively ​

Master the art of setting up default and fallback images to ensure every post has a featured image, no matter what. Essential for professional site appearance.

Overview ​

Default/fallback images serve as a safety net when no other image generation method succeeds. This prevents posts from appearing without featured images.

Why Fallback Images Matter:

  • Professional appearance
  • Consistent layout
  • Better social media sharing
  • Improved SEO
  • Enhanced user experience

Understanding the Fallback Hierarchy ​

Priority Order ​

When AFI tries to set a featured image, it follows this priority:

The behavior depends on which generation method you select in Settings > General:

  • Find in post — Uses first image found in post content
  • Generate from title — Creates an image from the post title
  • Find or generate — Tries to find an image in content; if none, generates from title
  • Find or use default image — Tries to find an image in content; if none, uses the default image
Example: "Find or use default image" method
1. Existing Featured Image (skipped if already set)
   ↓ (if none)
2. First Content Image
   ↓ (if none found)
3. Default/Fallback Image

Key Point: Fallback images only appear when all other methods fail or are unavailable.

Types of Fallback Images ​

1. Site-Wide Default ​

Single image for entire site:

Note: To use the default image, set the generation method to "Find or use default image" in the General tab.

Best for:

  • Simple sites
  • Consistent branding
  • Minimal content variety

Note: Currently, Auto Featured Image supports a single site-wide default image. Category-based, tag-based, and per-post-type defaults are not available in the current version.

Content Ideas for Default Images ​

1. Branded Placeholder ​

What to include:

  • Logo or site name
  • Tagline
  • Brand colors
  • Simple pattern/texture

Example:

┌─────────────────────────────────┐
│                                 │
│      [Your Logo]                │
│                                 │
│   Your Tagline Here             │
│                                 │
│   yoursite.com                  │
│                                 │
└─────────────────────────────────┘

2. Category Icon/Symbol ​

Design approach:

  • Icon representing category
  • Category name
  • Subtle background

Example for "Technology":

┌─────────────────────────────────┐
│                                 │
│      [Laptop Icon]              │
│                                 │
│      TECHNOLOGY                 │
│                                 │
└─────────────────────────────────┘

3. Generic Stock Photo ​

Select images that are:

  • Professional
  • Versatile (fit many topics)
  • High quality
  • Licensed for use

Examples:

  • Blurred background with light overlay
  • Abstract patterns
  • Geometric designs
  • Nature scenes (universal appeal)

4. Solid Color with Text ​

Minimal approach:

Background: Brand color
Text: Post title or site name
Font: Brand font
Style: Clean, readable

Example:
┌─────────────────────────────────┐
│  (Solid blue background)        │
│                                 │
│  Read More Articles             │
│  YourSite.com                   │
│                                 │
└─────────────────────────────────┘
