The agent can produce on-brand work with just a written anchor, but generations get sharper the moment you give it actual brand assets to reference. This page covers what’s worth bringing in and how to wire each one up.Documentation Index

Logos
The single most common cause of off-brand outputs is the model trying to recreate a logo from scratch. Don’t make it guess.Drag your logo file onto the canvas
PNG or SVG both work. Transparent backgrounds preferred. The file appears as an image node on the canvas.
Connect it to the image generations that need it
Drag an edge from the logo node into your output image node, or use
@logo (or whatever you’ve named it) inside a prompt.Fonts
Two paths depending on how strict you need to be: Path A: Brand guidelines paste-in. If you have a one-pager showing your fonts in use (H1 / H2 / body / display, all visible), paste an image of it onto the canvas and connect it to your image nodes. GPT Image 2 is good at recognizing fonts in a reference image and replicating them in output. Not pixel-perfect, but usually close enough to read as on-brand. Path B: Studio node for exact typography. When the type has to be exact (legal copy, headline that uses your custom font), generate the background without text, then use a Studio node to overlay the text layer. The Studio node is a layered editing surface where you can add layers, drop in text, and position elements precisely. You can upload a custom font file (.otf or .ttf) and use it directly in the layer panel. The Studio node also handles other “last mile” edits: positioning a logo precisely, adding a CTA button, dropping in a price tag. Most marketers end up using it for the final polish step without leaving the canvas.Pack shots and product photos
If your product has a specific shape, color, or detail that the model keeps getting wrong, a pack shot is the fastest fix.- Drop one or more clean product photos onto the canvas.
- Connect them to your image nodes as image-to-image references.
- In the prompt: “Use this exact product. Don’t restyle, recolor, or modify it — only change the surrounding scene.”
Group them as a unified group
Cmd+G for a normal group, or right-click → “Unified group”. A unified group exposes a single output port — so you drag one edge instead of one per image.Mood boards and style references
Got a Pinterest board, a competitor ad, or an existing campaign whose look you want to mirror? Use the Image Style Analysis template.Add the Image Style Analysis template
From the templates menu, pick “Image style analysis”. It drops onto the canvas as a pre-configured text node. Connect the unified group to it.
Run the text node
The template analyzes the images and outputs a detailed style description — palette, lighting, composition, mood, shot type.
Product detail pages (PDPs)
You don’t have to download every product photo manually. Paste a PDP URL into the agent chat and the agent will scrape the page — pulling product dimensions, materials, colors, copy, and reference imagery — into a text node you can reuse. Example brief:What to leave off the canvas
Not everything needs to be a reference. Some asset types are noise more than signal:- Past ads that don’t represent the new direction. If you’re refreshing the look, old assets will pull the agent back toward the look you’re trying to leave.
- Generic stock imagery. Unless it specifically matches your brand, it dilutes the reference.
- Low-resolution or compressed JPGs. The model struggles to extract style from heavily compressed images. Use the highest-quality source you have.
Image editing tools on the canvas
Once you have a generated image, you don’t always need to start over to make a change. A few tools live directly on each image node:- Edit Image — open the image in a quick editing surface for small tweaks.
- Inpaint — draw a mask over an area, then describe what should fill it. Useful for removing or replacing a specific element without re-running the whole generation.
- Remove Background — exactly what it sounds like. Outputs a transparent PNG.
- Upscale — increase resolution after generation if you started at 1K and want to ship at 2K or 4K.
- Studio node — for layered editing with text overlays, see the Fonts section above.
Inpaint is improving but isn’t always the right tool. For things like “remove the text from this image,” an image-to-image regeneration with a prompt like “recreate this exactly, but remove all text apart from the @logo” often produces cleaner results than masking. Try the image-to-image route first; reach for Inpaint when you need to keep most of the image untouched but change one specific region.
