How to Generate Images with OpenClaw: 5 Methods Compared

One of the most common questions in the OpenClaw community: "How do I get my lobster to generate images?"

Good news — there are multiple ways, from zero setup to professional-grade. Here are 5 methods, ranked from easiest to most powerful.

---

Method 1: Use the Built-in Skill (Zero Setup)

Every OpenClaw install ships with openai-image-gen. If you have an OpenAI API key configured, you already have image generation.

Just say:

"Generate an image of a sunset over mountains"

That's it. Your lobster will use DALL-E 3 or Nano Banana (depending on your OpenAI config) to generate the image.

Pros: Zero additional setup Cons: Limited to OpenAI models, basic text-to-image only Cost: ~$0.04-0.08 per image

---

Method 2: Install Nano Banana Pro (Best Quality/Cost Ratio)

Google's Gemini 3 Pro image model is currently one of the best for text rendering and precise edits.

Setup (3 minutes):

clawhub install nano-banana-pro

Then add your Google API key to your OpenClaw config. Done.

Try it:

"Generate a product photo of white sneakers on a marble surface, studio lighting"

Pros: Excellent quality, great text rendering, good price Cons: Single model only Cost: ~$0.05-0.10 per image

---

Method 3: Install Seedream (Cheapest High-Quality Option)

ByteDance's Seedream 4.5 is remarkably cheap and produces photorealistic results.

Setup (5 minutes):

clawhub install seedream-image-gen

You'll need a Volcengine (火山引擎) account and API credentials.

Try it:

"A Chinese woman in traditional hanfu, cherry blossoms in background, golden hour"

Pros: Cheapest per image, excellent with photorealistic scenes Cons: Volcengine account required (easier for China-based users) Cost: ~$0.02-0.05 per image

---

Method 4: Install a Multi-Model Skill (Midjourney + More)

Want Midjourney in your lobster? There are two main options:

Option A — image-gen (via Legnext):

clawhub install image-gen

Access Midjourney, Flux, SDXL, and Nano Banana through Legnext.ai.

Option B — IMA Studio:

clawhub install ima-image-ai

Access Midjourney, Nano Banana Pro, Seedream, and more through one IMA API key.

Try it:

"Use Midjourney to create a cyberpunk cityscape at night, neon lights, rain"

Pros: Multiple models, one skill Cons: Third-party API layer, credit-based pricing Cost: ~$0.05-0.15 per image

---

Method 5: Go All-In — Images + Video + Music

If you want your lobster to be a complete media production studio:

clawhub install ima-all-ai

This single skill covers:

• 🖼️ Images: Midjourney, Nano Banana, Seedream
• 🎬 Video: Wan 2.6, Kling, Veo, Sora
• 🎵 Music: Suno, DouBao

Try it:

"Create a 15-second product video for this coffee mug with background music"

Pros: Everything in one place Cons: Credit-based, requires IMA account Cost: Credits vary by model and media type

Pro Tips

1. Set exec timeout to 300+ seconds. Image generation can take longer than the default timeout. Add this to your config to avoid premature kills.

2. Use image-to-image when possible. Text-to-image often "hallucinates" product details. If you have a reference photo, image-to-image is more accurate. (Lesson I learned the hard way with an iPhone that didn't look like an iPhone.)

3. Save your best prompts. Create a prompts/ folder in your workspace. Good prompts are reusable assets.

4. Check security before installing. Always review SKILL.md source on GitHub before installing any ClawHub skill. The VirusTotal integration on ClawHub is your friend.
