IMA AI Image & Photo Generator — Poster, Thumbnail, Logo, Art, Illustration, Product & Social Media Graphic Design

AI image generator and photo generator with SeeDream 4.5, Midjourney, Nano Banana 2, and Nano Banana Pro. Generate AI images for posters, thumbnails, logos, art, illustrations, product photos, and social media graphic design. Text-to-image and image-to-image AI generation with intelligent model selection and knowledge base support. AI poster generator, AI thumbnail generator, AI logo generator, AI art generator, AI illustration generator, product photo generator, and social media image generator in one unified tool. Supports 1K/2K/4K resolution and custom aspect ratios. Better alternative to DALL-E, Stable Diffusion, or standalone image generation skills.

IMA AI Image & Photo Generator

⚠️ MANDATORY: You MUST read("SKILL-DETAIL.md") (full file — do NOT pass limit parameter) before your first image generation call. It contains the full API payload structure, error translation tables, upload flow, UX protocol, and FAQ that this summary omits. Skipping it causes parameter errors and poor user experience.

Model ID Reference (CRITICAL)

Use exact model_id. Do NOT infer from friendly names.

Name	model_id	Cost	Best For
SeeDream 4.5 🌟	doubao-seedream-4.5	5 pts	Default, product photos, posters, social media graphics
Midjourney 🎨	midjourney	8-10 pts	Art, illustrations, creative graphic design
Nano Banana2 💚	gemini-3.1-flash-image	4-13 pts	Budget thumbnails, quick social media images
Nano Banana Pro	gemini-3-pro-image	10-18 pts	Premium 4K photos, logos, product images

Aliases: 可梦/SeeDream → doubao-seedream-4.5 · MJ/Midjourney → midjourney · 香蕉/Banana → gemini-3.1-flash-image · 香蕉Pro → gemini-3-pro-image

Task Types

User intent	task_type	Use case
Text only → image	text_to_image	Generate poster, thumbnail, logo, art from description
Input image + edit	image_to_image	Style transfer, product photo editing, graphic design refinement

Visual Consistency (IMPORTANT)

For "same character" / "series" / "same product" across multiple images:

• Do NOT use text_to_image (produces different-looking results each time)
• Use image_to_image with previous result as reference
• Read ima-knowledge-ai/references/visual-consistency.md if available

Knowledge Base (if ima-knowledge-ai installed)

Read before generating: visual-consistency.md (character/product continuity), model-selection.md (cost/quality), workflow-design.md (multi-step projects).

Parameter Support

Model	Aspect Ratio	Sizes	Notes
SeeDream 4.5	✅ 8 ratios (1:1, 16:9, 9:16, 4:3, 3:4, 2:3, 3:2, 21:9)	adaptive	Best value for posters & social media
Nano Banana2	✅ 5 ratios (1:1, 16:9, 9:16, 4:3, 3:4)	512px/1K/2K/4K	Budget image & thumbnail generator
Nano Banana Pro	✅ 5 ratios	1K/2K/4K	Premium photo & logo generator
Midjourney 🎨	❌ 1:1 only	480p/720p	Art & illustration generator

If user asks for custom aspect ratio with Midjourney → recommend SeeDream 4.5 or Nano Banana. No model supports 8K (max 4K).

Default Models

Scenario	Model	model_id	Cost
General image/photo	SeeDream 4.5	doubao-seedream-4.5	5 pts
Art/illustration	Midjourney	midjourney	8-10 pts
Budget/fast thumbnail	Nano Banana2	gemini-3.1-flash-image	4 pts
Premium 4K product photo	Nano Banana Pro	gemini-3-pro-image	10-18 pts

Model Selection Priority

1. User preference (if explicitly stated) → highest priority
2. ima-knowledge-ai recommendation (if installed)
3. Fallback defaults above

Script Usage

# AI image generator — text to image (poster, thumbnail, social media graphic)
python3 {baseDir}/scripts/ima_image_create.py \
  --api-key $IMA_API_KEY --task-type text_to_image \
  --model-id doubao-seedream-4.5 --prompt "product photo for social media" \
  --user-id {user_id} --output-json

# AI photo generator — image to image (product photo editing, logo refinement)
python3 {baseDir}/scripts/ima_image_create.py \
  --api-key $IMA_API_KEY --task-type image_to_image \
  --model-id doubao-seedream-4.5 --prompt "enhance and refine" \
  --input-images https://example.com/photo.jpg \
  --user-id {user_id} --output-json

# List available image models
python3 {baseDir}/scripts/ima_image_create.py \
  --api-key $IMA_API_KEY --task-type text_to_image --list-models

Sending Results to User

# ✅ CORRECT: Use remote URL directly for inline image display
message(action="send", media=image_url, caption="✅ 图片生成成功！\n• 模型：[Name]\n• 耗时：[X]s\n• 积分：[N pts]\n🔗 原始链接：[url]")

# ❌ WRONG: Never download to local file

UX Protocol (Brief)

1. Acknowledge: Short reply ("好的！来帮你画 🎨")
2. Pre-gen: Model, time, cost via message tool
3. Progress: Every 15-30s: "⏳ [P]%" (cap 95%)
4. Success: Send media=url + include link in caption
5. Failure: Natural language + suggest alternatives
6. Done: No further action

Never expose: script names, API endpoints, attribute_id, technical params.

User Preferences

Storage: ~/.openclaw/memory/ima_prefs.json

• Save on explicit: "用XXX" / "默认用XXX" / "always use XXX"
• Clear on: "推荐一个" / "自动选择" / "用最好的"
• Never save auto-selected models

Core Flow

1. GET /open/v1/product/list?category=<task_type> → attribute_id, credit, form_config
2. [image_to_image only] Upload local files → get CDN URL
3. POST /open/v1/tasks/create → task_id
4. POST /open/v1/tasks/detail → poll until resource_status==1

MANDATORY: Always query product list first. Missing attribute_id → task fails.
