How to Generate Images for Blog Posts (The Modern Way)
Used to be: write the post, search Unsplash for 20 minutes, settle for a generic laptop photo.
Now: write the post, paste it into a tool, get back images that actually match the content.
This is how the new workflow looks - and why nobody who's tried it goes back.

The Old Workflow (Why It Was Broken)
The classic stack:
- Write the article (good)
- Open Unsplash / Pexels (eh)
- Search for vaguely related photos (bad)
- Realize 5 other blogs used the same shot (worse)
- Open Photoshop or Canva to make a header (extra bad)
- Export at the wrong size (worst)
- Publish 2 hours late (catastrophic)
Most bloggers spend more time on images than writing. Read that twice.
What Changed
Two things:
- AI image quality crossed the "good enough for blog" line in late 2024.
- AI image speed crossed "faster than searching stock" by 2025.
Once both happened, "generate" beat "search" for the median blogger.
The Modern Workflow
Three minutes, three steps.
Step 1: Paste your post
Drop your article (or just title + intro) into Postpix. The tool reads it - so the images match the content, not a keyword guess.
Step 2: Pick a style and generate
Pick once. Stick with it across posts.
A few that work for blog content:
- Ghibli (details)
- Editorial photoreal (details)
- Isometric (good for SaaS / tech)
- Sticker / cartoon (good for casual, indie content)
Step 3: Download and place
Header at the top. One or two inline images at major section breaks. Done.
A Prompt Formula That Saves Time
If you want more control, use this:
Save it. Reuse it. Change only the subject between posts.
Why "Generate" Beats "Search" Now
Three reasons:
- Match - generated images reflect the actual post, not a tag.
- Uniqueness - your readers haven't seen the image on 40 other blogs.
- Consistency - every post can share a style without a brand pack.
Stock photos still have a place (real product shots, real people, news). For everything else, generation wins.
The Stock Photos vs AI breakdown has the longer version.
How Many Images Per Post?
A pattern that works for most blogs:
| Post length | Images | Where |
|---|---|---|
| 500-800 words | 1 | Header only |
| 800-1500 words | 2-3 | Header + 1-2 section breaks |
| 1500-3000+ words | 4-6 | Header + every major section |
Don't over-image. Reader fatigue is real, and so is page weight.
The Mistakes to Avoid
- Different style every post - kills brand. Pick one, lock it.
- Photoreal AI of people - still uncanny valley. Skip faces unless you're sure.
- Cluttered backgrounds - blog images get cropped on mobile. Keep them clean.
- No alt text - generated or not, write alt text. Accessibility + SEO.
Who's Doing This Well
- SaaS founders shipping weekly product blogs
- Newsletter writers using AI images in email previews
- Freelancers who can't justify a designer line item
If you publish a post a week, you're the target.
