# Custom Header Image

Add a custom header image to your survey

Add a custom header image, logo or background to make your Zigpoll survey a seamless part of your brand.

#### Step #1: Go to Your Design Settings

* To change it for **all surveys**: go to **Settings → Design Defaults**.
* To change it for **a specific survey**: open the survey and go to **Settings → Design**. If the survey uses your account defaults, turn on **Override Design Settings** first.

#### Step #2: Pick the Right Image Field

Each Design tab has its own images. Choose the tab for where the survey appears:

| Where                                  | Tab             | Field                                                                             | Uploads are resized to                        |
| -------------------------------------- | --------------- | --------------------------------------------------------------------------------- | --------------------------------------------- |
| Survey on your website                 | **On-Site**     | **Background Image**, under **Colors** — fills the survey's background            | 1080 × 300 px, cropped                        |
| Survey on your website, modal position | **On-Site**     | **Logo Image**, **Side Image** and **Overlay Image**, under **Edit Modal Design** | 300 px tall (logo)                            |
| Hosted survey page (your survey link)  | **Survey Page** | **Logo** (with **Logo Placement**) and **Background Image**                       | 700 px tall (logo), 2400 px wide (background) |
| Email surveys                          | **Email**       | **Logo** and **Header bar**                                                       | —                                             |

The **launcher** — the button that opens an on-site survey — has its own image. See [Custom Launcher Image](/tutorials/custom-launcher-image.md).

#### Step #3: Upload Your Image

1. Upload the image into the field. You can drag and drop it, or click the box to open a file upload window.
2. Click **Save Changes** to push your changes live.

{% hint style="info" %}
**Logo cut off or missing?** Uploads are cropped or resized to the sizes above, so leave some space around a logo that sits on a background image. A tall logo can crowd the questions on short screens: use a shorter logo, or put it on the **Survey Page** tab instead. Surveys in Shopify checkout blocks don't show these images; see [Shopify checkout limits](/installation/shopify-checkout-limits.md).
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.zigpoll.com/tutorials/custom-header-image.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
