How do AI image generators like Midjourney actually compare to stock photo sites for blog content?

It's not a straightforward 'one is better' answer. It depends on what you need the image to do. Stock photo sites like Unsplash or Shutterstock give you real photographs. Real people, real places, real lighting. They're safe. You know exactly what you're getting. AI image generators like Midjourney or DALL-E 3 create images from scratch based on your description. You can get exactly the scene you imagine — a 'robot teaching a cooking class in a sunlit kitchen' — that no stock site will ever have. The catch? Control. With stock photos, you search and pick. Five minutes, done. With AI, you're prompting, regenerating, tweaking. 'Make the robot look friendlier. No, less creepy. Now the lighting is wrong.' I've spent 45 minutes getting one usable image. The hands might look weird. Text in the image will almost certainly be garbled. For quick, professional blog headers, stock photos win on speed. For unique, attention-grabbing visuals that nobody else has, AI wins on originality. Here's the practical tip most guides miss: use both. Pull a stock photo for the hero image where you need reliable quality. Use AI to generate custom illustrations for concepts that are hard to photograph — abstract ideas, futuristic scenarios, metaphors. That combination gives you efficiency and distinctiveness without the frustration of trying to make AI do everything. Also, check the licensing. Some stock sites now include AI-generated images in their libraries, which blurs the line even further. Sources: Midjourney terms of service, Unsplash license agreement, 2025.
