Adding images to your contest makes it more visually appealing and helps communicate your brand. You can add a header image and a logo, both optional.

## Header Image

The header image appears as a full-width banner at the top of your contest, above the title.

**To add a header image:**

1. Go to the **Design** tab of your contest.
2. In the **Header Image** section, click **Upload image**.
3. Select an image file from your computer.
4. The image uploads to your Shopify file storage and appears in the preview.

**Requirements:**
- Maximum file size: **10 MB**
- Supported formats: JPEG, PNG, GIF, WebP, SVG

**Tips:**
- Use a wide, landscape-oriented image for best results — it displays full-width with a max height of 200px and is cropped to cover.
- Keep important content centered, as edges may be cropped on different screen sizes.

**To replace or remove:**
- Click the image to upload a replacement.
- Use the remove button to delete the header image entirely.

## Logo

The logo appears above the contest title as a smaller, contained image. It's great for adding your brand mark or a contest-specific icon.

**To add a logo:**

1. Go to the **Design** tab of your contest.
2. In the **Logo** section, click **Upload image**.
3. Select an image file from your computer.

**Requirements:**
- Maximum file size: **10 MB**
- Supported formats: JPEG, PNG, GIF, WebP, SVG

**Logo size:**
Use the size slider to adjust the logo dimensions. The logo displays as a square with rounded corners.

- Minimum: **1px**
- Maximum: **200px**
- Default: **48px**

The logo uses `object-fit: contain`, so it won't be stretched or distorted regardless of the original image proportions.

## How Images Display

| Location | Header Image | Logo |
|---|---|---|
| Standalone contest page | Full-width banner at top | Above title, centered |
| Theme blocks (popup/form) | Shown if available | Shown if available |
| Mobile devices | Scales to fit width | Uses configured size |

Both images load lazily for better performance and include proper `alt` attributes for accessibility.
