AI Image Generation for WordPress

Stock photos are expensive and generic. AI image generation creates unique, on-brand visuals from text descriptions — at a fraction of the cost and without licensing concerns (depending on the tool).

AI Image Tools for WordPress

• SiteICO AI Image: Generate featured images directly in your content editor. Powered by Flux and Stable Diffusion — no external account needed.
• DALL-E 3: OpenAI's image model, accessible via ChatGPT Plus or API. Excellent for photorealistic and artistic styles.
• Midjourney: Highest quality for artistic and branded imagery. Requires Discord and a subscription. Not WordPress-integrated — download and upload manually.
• Stable Diffusion: Open-source, self-hostable. Various WordPress plugins connect to local or cloud Stable Diffusion instances.

Prompting for Blog Content

Effective prompts for blog featured images: specify the mood, style, subject, and any technical requirements. Example: "A clean, professional illustration of a person using a laptop to manage a website dashboard, flat design style, blue and white color palette, no text."

Best Practices

• Generate at 1200×630px for blog featured images (optimal for social sharing)
• Always add descriptive alt text to AI images for accessibility and SEO
• Check your AI tool's commercial use license before publishing
• Keep a consistent style prompt across your site for visual brand consistency

SEO Considerations

AI images pass Google's quality guidelines when they are relevant to the content and properly attributed. Use descriptive filenames and alt text. Compress generated images — they are often large raw PNG files.
