<h4>🎨 Generation Methods Explained</h4>
1. First Content Image (Free) 
Automatically scans your post content and selects the first suitable image that meets your quality requirements. Perfect for blogs and news sites where articles already contain relevant images. Smart detection ensures only high-quality images become featured thumbnails. No API keys or external services required.
2. AI Generation with OpenAI DALL-E (Optional) 
Create completely unique, contextual images using cutting-edge AI technology. The plugin analyzes your post content (title, paragraphs, or full text) and generates a detailed prompt using GPT models (GPT-4, GPT-4o, or GPT-4o-mini). DALL-E then creates a custom image matching your content perfectly. Choose from natural or vivid styles, resolutions up to 1024×1792, and multiple language options. Requires OpenAI API key (costs ~$0.04-$0.08 per image).
3. Generate from Title (Free) 
Transform post titles into professional custom graphics with text overlays. Fully customize width, height, background color, text color, and font size. The real-time live preview shows exactly how your thumbnail will look before generating. Perfect for social media sharing and maintaining consistent branding. Uses local GD Library—no external services needed.
4. Search or Generate (Free) 
Smart fallback strategy that combines the best of both worlds. First attempts to find a suitable image in your post content. If none found, automatically generates a custom title-based graphic. Ensures every post gets a featured image without manual intervention. Ideal for mixed content where some posts have images and others don’t.
5. Use Default Image (Free) 
Professional fallback system using a preset image from your WordPress media library. When no suitable image is found in content, the plugin automatically uses your chosen default. Perfect for maintaining consistent branding across posts without images. Great for podcasts, text-heavy content, or specific categories.
<h4>🏆 Why Choose AI Thumbnails Maker?</h4>
