Image Generation
Generate images with the imagesgenerate tool. It handles text-to-image, image-to-image (pass referenceimages), and multi-image composition. By default (model="auto") it picks the best model for the request; set model to choose one.
Requirements
This skill assumes the Hyper MCP is connected to your agent so the images_generate tool is available. For brand-consistent ad creative work, Firecrawl must also be configured under your Hyper integrations.
Call shape
images_generate(
requests=[{"id": "ad1", "prompt": "A polished SaaS ad, clean composition"}],
aspect_ratio="16:9", # "1:1" (default), "9:16", "16:9", "4:5", "2:3", "3:2", "3:4", "4:3", "21:9", ...
quality="standard", # "draft" | "standard" | "high"
n=1, # 1-4 images per request
model="auto", # see "Choosing a model" below
)
- Image-to-image / brand references: put files in the request:
requests=[{"prompt": "Compose into a gift basket", "reference_images": ["file1", "file2"]}].
- Reproducible output: pass
seed=....
- Ground in real-world search: pass
use_search=True.
- Do not display image URLs — they render automatically in chat.
Choosing a model
model="auto" is the right default. Override only when the task clearly calls for a specific model:
| Task |
model |
| First-pass concepts / quick ad ideation |
gpt-image-2 |
| Image-to-image with references, high-resolution refinement, broad aspect ratios |
nano-banana |
| Readable text inside the image (posters, labels, infographics) or search-grounded scenes |
nano-banana-pro |
| Product photography, material/fabric fidelity, accurate spatial depth |
seedream-4.5 |
See [references/image-prompting.md](references/image-prompting.md) for per-model prompt-writing tips.
Branded / website ad creatives — extract branding first
If the user gives a website URL and wants on-brand creatives:
- Call
firecrawlbrandingextract with the URL → returns brand colors, fonts,
personality/tone, and saved image files (logo, favicon, og_image).
- Optionally
firecrawlurlsscrape with formats=["screenshot"] for visual context.
- Write the prompt using the actual hex colors, font names, and tone, and pass the
logo fileid in referenceimages.
The branding result's file field is a JSON data file, NOT an image — never pass it as a reference. Only logo.fileid and images.*.fileid are usable images.
Higher-level workflows
For multi-shot product or marketplace work, prefer the workflow tools — they preserve product identity and return structured results:
imagesproductphotoshoots_create — multi-shot product photography (studio,
lifestyle, hero, carousel, ad pack). See [references/product-photoshoot.md](references/product-photoshoot.md).
imagesmarketplacecards_create — marketplace listing image sets (Amazon main +
secondary, A+ modules, Shopify). See [references/marketplace-cards.md](references/marketplace-cards.md).
Reminders
- Do NOT display image URLs to the user — they show automatically in chat.
- Refine vague prompts unless the user wants verbatim generation.
- Match
aspect_ratio to intent (social, print, web).
- Use
quality="high" for production, "draft"/"standard" while iterating.
- Generated
fileids can be reused as referenceimages in later calls.
- For website brand work, call
firecrawlbrandingextract before generating.
