Use OTTO PPC's AI image generation to create Landscape, Square, Portrait, and Vertical image assets for your Performance Max campaigns — by writing a custom prompt, refining a generated result, attaching a reference image, or using your Brand Vault.

## 🖼️ Where AI Image Generation Appears in PMAX

The **Generate with AI** option is available inside any Performance Max (PMAX) campaign under **Image Assets**. It supports the four image formats required by Google Ads:

- **Landscape** — 1.91:1 ratio, used for display and banner placements
- **Square** — 1:1 ratio, suited for mobile and discovery feeds
- **Portrait** — 4:5 ratio, suited for mobile and social feeds
- **Vertical** — 9:16 ratio, used for YouTube Shorts and Google Discover Stories placements

To open the panel, go to your PMAX campaign in OTTO PPC, click **Image Assets**, select the image format you need, and click **Generate with AI**.

## ✏️ How to Write a Prompt for AI Image Generation

Your typed prompt is the AI's primary instruction. Be specific — describe the subject, setting, and visual style you want to see. The more concrete your description, the more targeted the output.

**Steps:**

1. Open the **Generate with AI** panel for your chosen image format.
2. Type your prompt in the prompt field. For example: "A professional woman reviewing analytics on a laptop in a modern, sunlit office — clean, minimal style."
3. Click **Generate**.
4. Review the image previews returned by the AI.
5. Select the image you want and click **Add to Assets** to save the image to your campaign.

**What happens next:** The image is added to your Image Assets list for this format. Google Ads recommends uploading at least 3–5 images per format for optimal delivery.

**Tips for stronger prompts:**

- Lead with the main subject, then add the setting, then the mood or visual style.
- Use concrete descriptors — "bright natural light" rather than "nice lighting."
- Keep prompts action-focused; describe what you want rather than what to avoid.

Generated previews appear within a few seconds of clicking **Generate**.

## 🔁 How to Use the Refine Button on a Generated Image

The **Refine** button adjusts a selected generated image based on a new instruction — without regenerating from scratch. Use it when you like the overall composition but want to change a specific element such as color, background, or lighting.

**Steps:**

1. Generate an initial image using a prompt (see the prompt section above).
2. Select the image you want to adjust from the preview set.
3. Click **Refine**.
4. Enter your adjustment instruction — for example: "Change the background to white" or "Make the lighting warmer and softer."
5. Click **Apply**.

The AI updates only the elements you described while preserving the rest of the image. The refined version appears alongside the original so you can compare before choosing. Click **Add to Assets** to save the image to your campaign.

## 📎 How to Attach a Reference Image for AI Generation

A **reference image** gives the AI a visual example — style, color palette, or composition — to draw from alongside your prompt. Use it when you have an existing asset whose visual style you want the generated output to match.

**Steps:**

1. Open the **Generate with AI** panel.
2. Click **Attach Reference Image** (or the image upload icon in the panel).
3. Upload your reference file from your device (JPEG or PNG).
4. Enter a prompt describing how the AI should use the reference — for example: "Generate a product lifestyle image in the same color palette and minimalist style as the reference."
5. Click **Generate**.

The AI combines your prompt and reference image to shape the output. To remove the reference before generating, click the **X** on the uploaded thumbnail. Click **Add to Assets** to save the image to your campaign.

## 🏛️ How to Use Brand Vault for AI Image Generation

The **Brand Vault** stores your approved brand assets — logos, color palettes, and visual guidelines — so the AI can apply your brand identity automatically to every generated image. This eliminates re-uploading or re-describing brand elements each time you generate.

**Steps:**

1. Open the **Generate with AI** panel inside your PMAX Image Assets section.
2. Select **Brand Vault** from the panel options.
3. Choose the brand profile you want to apply.
4. Enter your image prompt as usual.
5. Click **Generate**.

The AI applies your brand's colors and visual style to the generated image. If Brand Vault is not yet configured, go to **Header (apps-grid icon) → More Features → Brand Vault** to add your brand assets before using this option. Click **Add to Assets** to save the image to your campaign.

**⚠️ Known issue:** If you encounter an error when launching your PMAX campaign after adding image assets, this is a known issue currently being resolved. Refresh and retry, or contact support if the error persists.

**🎯 You can now generate, refine, and brand-match PMAX image assets in all four formats directly inside OTTO PPC. To ensure every AI-generated image stays on-brand, keep your assets up to date in Header (apps-grid icon) → More Features → Brand Vault whenever your visual identity changes.**
