# Product Personalizer - Live Mockup Settings
## What is Product Personalizer/Live Mockup?
Live Mockup allows shoppers to see their customizations applied to the product **in real time** before adding it to the cart. As customers select options (text, images, colors, buttons, swatches, etc.), the product preview updates instantly, showing exactly how the final product will look.
## What Live Mockup Can Do
Live Mockup works seamlessly with your product options and variants to:
* Instantly reflect option changes on the product image
* Display text inputs, uploads, or selections directly on the product
* Update visuals without page reloads
* Support multiple option types: [Text box](https://help.optis.me/en/article/create-a-textbox-xq9qlw/), [File upload](https://help.optis.me/en/article/create-a-file-upload-1bdv45s/), [Image & Color Swatch](https://help.optis.me/en/article/create-a-swatch-4cklgo/) (Note: **Text box’s live mockup** can be combined with [Color picker](https://help.optis.me/en/article/create-a-color-picker-ovw276/), [Color Swatch](https://help.optis.me/en/article/create-a-swatch-4cklgo/), Font Picker (coming soon) to preview text color and styling in real time).
Customers can interact with options and immediately see the result — no guessing, no surprises.

| **Paid add-ons & upgrades** | Gift wrapping styles- Extra decorations or finishes- Paid engraving or personalization | Visualizing upgrades makes added costs easier to justify |
| **Made-to-order or non-returnable items** | Personalized or custom-built products | Visual confirmation is critical when products can’t be resold or returned |

## How To Set Up
### A. Explaining the setting panels
1. Live Mockup tab
For options that support Live Preview (Text box, File Upload, Swatch), you’ll see a **Live mockup** tab located at the top right.
* What it does: The **Live mockup** tab controls how the option appears in the live preview on your product page.
* How it works with Option Content tab: The Product personalizer uses values from Option Content, so we recommend setting those up first.
2. Preview panel: **Select background**
When Live Mockup is enabled, start by selecting the Background first.
**Select background**
**Preview**\
After choosing a background, decide where the preview should appear:
| **All product images (default)** | The preview appears on all product images. When customers switch between images, the preview remains visible on each image. |
| -------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **First product image only** | The preview appears only on the first product image. If customers switch to another image, the live preview will no longer be shown. |
| **Variant image only** | The preview appears only on the selected variant’s image. When customers change variants, the background updates to the corresponding variant image, and the preview is shown on that image instead of the main product image. |
| **Last product image only** | The preview appears only on the last image in the product’s media list. |
| **Specific product image** | The preview appears only on a specific product image, based on its position in the product’s media list. Enter the image order number to select which image the preview should appear on. |
**Note:** The preview may look smaller during setup. Use **Zoom In** to check details. The final preview on your live store will display as expected.
