AI Images: Useful Tool or Risky Shortcut?

AI image generation tools like Midjourney, DALL-E, and Adobe Firefly have made it possible to create custom visuals without hiring a photographer or designer. For Irish businesses building or updating websites, this sounds brilliant — but there are important considerations before you fill your site with AI-generated images.

The technology has improved rapidly. Modern AI image generators can produce professional-looking photos, illustrations, icons, and graphics. But 'can' doesn't always mean 'should'.

Companies like Stability AI and OpenAI have invested significant resources into making image generation accessible and commercially viable. Adobe's Firefly is trained on licensed content, making it the safest option for businesses concerned about copyright. Meanwhile, smaller companies are leveraging AI images strategically to compete with larger organisations that have bigger creative budgets.

When AI Images Work Well

AI image generation is genuinely useful in specific scenarios. It's not a universal replacement for professional photography, but it fills gaps that stock photos never could.

• Blog post illustrations and header images where custom photography isn't practical
• Conceptual graphics for abstract topics (cybersecurity, data, AI itself)
• Placeholder visuals during website development before final photography is ready
• Social media graphics where volume is high and budgets are tight
• Icon and pattern generation for design elements
• Rapid prototyping and mood boards for design concepts

When AI Images Don't Work

There are situations where AI images actively harm your website's credibility. Knowing when not to use them is just as important.

• Team photos — visitors can spot AI-generated faces, and it destroys trust
• Product images — customers need to see the actual product they're buying
• Testimonial photos — fake-looking photos undermine genuine reviews
• Location shots — if you claim to be in Dublin, show actual Dublin
• Any image that implies authenticity but isn't authentic

The Best AI Image Tools

Legal and Ethical Considerations

The legal landscape around AI-generated images is still evolving. Irish businesses need to be aware of several considerations, particularly as the EU AI Act comes into effect.

• Copyright ownership of AI-generated images remains legally uncertain in many jurisdictions
• Some AI tools train on copyrighted images, creating potential liability
• Adobe Firefly is trained on licensed and public domain content, making it safer for commercial use
• Always check the licence terms of your AI image tool before using images commercially
• Disclosure requirements may emerge — some platforms already require AI image labelling
• EU AI Act regulations may affect how AI-generated content must be disclosed

SEO Implications

AI images have specific implications for your website's SEO performance. Google hasn't penalised AI images specifically, but the way you implement them matters.

• Always add descriptive alt text — AI images need the same accessibility treatment as any image
• Optimise file sizes — AI generators often output large files that slow your site
• Use descriptive filenames rather than the random strings AI tools generate
• Don't use AI images to deceive users — misleading images can affect your site's E-E-A-T signals
• Original AI images are better than stock photos for uniqueness signals

Practical Tips for Implementation

1. Establish an AI image policy for your business — decide where AI images are and aren't appropriate
2. Always optimise AI images before uploading (compress, resize, convert to WebP)
3. Keep a record of prompts used to generate images for consistency
4. Mix AI images with genuine photography for authenticity
5. Review AI images carefully for artifacts, extra fingers, distorted text, or other telltale signs
6. Test how images look on mobile — what looks good at full size may not work on smaller screens

How should I optimise AI-generated images for my website?

AI-generated images need the same optimisation as any other image. First, follow standard image optimisation practices: convert to modern formats like WebP, compress without losing quality, and resize to appropriate dimensions. AI image tools often generate large files (2-3MB+), so compression is critical. Use tools like TinyPNG or ImageOptim to reduce file sizes. Also ensure your alt text is descriptive and includes relevant keywords. Properly optimised images load faster and contribute to both user experience and SEO.

Does Google penalise websites that use AI-generated images?

Google doesn't specifically penalise AI-generated images. However, Google does care about whether images serve user experience and whether they're used deceptively. Using AI images appropriately (like for illustrations and conceptual graphics) won't hurt your SEO performance. What can hurt is using AI images to mislead users or placing them where they create a poor user experience. The key is transparency and proper implementation. Google's focus is on how well your images serve your content and users, not on the image source itself.
