Most AI image problems (extra fingers, melted faces, garbled text, cluttered scenes, wrong proportions) come from asking for too much at once or leaving too much undefined. Fix them by simplifying the scene, describing the problem area explicitly, using a negative prompt where the tool supports one, generating several variations and adding text afterwards in a design app instead of inside the AI image. When an image is 90% right, edit or crop the bad part rather than starting over.
- Fewer subjects and simpler poses mean fewer errors.
- Hands, text and crowds are the hardest things for AI. Avoid or hide them when you can.
- Negative prompts list what you do not want, such as “blurry, extra fingers, watermark”.
- Always add headlines and logos yourself in a design tool.
- Generate variations quickly in the free AI Image Generator.
The perfect poster with six fingers
A coaching centre in Cumilla wants a poster for its new spoken English batch. The AI image is almost perfect: a confident student giving a presentation, warm classroom light, bright colours. Then someone notices the student’s raised hand has six fingers, and the whiteboard behind her says “ENGLSIH CLAAS”.
Nobody would have paid much attention to the finger count in real life. But once you see it, you cannot unsee it, and parents notice too. The good news is that both problems have simple fixes.
Common problems and how to fix them
| Problem | Why it happens | Fix |
|---|---|---|
| Extra or merged fingers | Hands have many possible poses and small parts | Hide hands (pockets, holding an object), choose simple poses, regenerate, or crop |
| Garbled text and signs | Many image models handle letters poorly | Ask for “blank sign” or “no text”, add text later in a design app |
| Distorted faces in groups | Small faces get few details | Fewer people, closer shot, or one main subject |
| Cluttered, busy image | Too many objects in the prompt | Limit to one subject and two or three supporting details |
| Wrong proportions | No scale reference | Mention size: “a small cup in her hands”, “wide shot” |
| Weird objects merging | Overlapping items confuse the model | Describe placement: “on the left”, “behind”, “separate” |
| Plastic-looking skin | Over-smoothed “beauty” defaults | Add “natural skin texture, candid photo, soft natural light” |
| Wrong colours | Colour not specified or conflicting | State the palette clearly and avoid mixing colour words for different objects |
How to use negative prompts
Some generators let you add a negative prompt: a list of things to avoid. Where available, a general-purpose negative prompt looks like this:
blurry, low quality, extra fingers, deformed hands, distorted face, watermark, text, logo, cropped head, duplicate
For a deeper look, read negative prompts explained. If your tool has no negative prompt field, write positive instructions instead: “sharp focus, hands hidden in pockets, clean background with no text”.
A step-by-step troubleshooting routine
- SimplifyRemove one subject, one prop and one adjective. Try again.
- Be explicit about the weak spot“Her hands are folded and resting on the desk.”
- Change the framingA closer or wider shot often removes the problem area.
- Generate variationsMake four to eight versions and pick the best rather than perfecting one.
- Edit, do not restartCrop, cover with a text box, or use an editing tool to repaint a small area.
- Add text lastPlace headlines, prices and logos in a design app.
Getting faces and people right
- One or two people work far better than a crowd.
- Describe expression and action simply: “smiling, looking at the camera, holding a book”.
- Mention age range and clothing for realism and cultural fit: “young Bangladeshi woman in a blue salwar kameez”.
- Avoid generating images that look like real, identifiable people.
Final checks before you publish
- Zoom in on hands, eyes, teeth and edges.
- Check any background text or signs.
- Check shadows and reflections make sense.
- Compress the file for web with the image compressor.
- Add descriptive alt text. See our alt text guide.

Frequently asked questions
Why does AI draw extra fingers?
Hands have many small parts and possible poses, which many image models find hard. Simpler poses, hidden hands or closer framing usually help.
How do I stop AI from adding text to images?
Ask for blank signs or “no text”, use a negative prompt if available, and add your own text later in a design app.
What is a negative prompt?
A list of things you do not want in the image, such as blurry, extra fingers, watermark or text. Not every generator supports it.
How do I make AI faces look more natural?
Use one or two people, a closer shot, natural light and words like natural skin texture and candid photo.
Should I edit AI images or regenerate them?
If the image is mostly right, crop or edit the problem area. Regenerate when the composition itself is wrong.
