+### Shareable Banner
+
+Sunday Comics includes an old-school shareable banner button in the footer that visitors can use to link back to your site. To enable it:
+
+1. Create a banner image (any size) and save it in `static/images/`
+2. Set the `BANNER_IMAGE` variable in `comics_data.py`:
+   ```python
+   BANNER_IMAGE = 'banner.jpg'  # Your banner filename
+   ```
+3. Set to `None` to hide the "Link to Me" section entirely:
+   ```python
+   BANNER_IMAGE = None  # Disables the shareable banner
+   ```
+
+When enabled, the banner appears in the footer with:
+- A preview of the banner image
+- A collapsible "Get code" section with copy-paste HTML
+- Fully keyboard accessible (Tab to navigate, Space/Enter to expand)
+- Automatic URL generation using your `SITE_URL` setting
+
+Visitors can click "Get code" to reveal embeddable HTML they can paste on their own websites, creating a link back to your comic. Perfect for webrings, link exchanges, and building community!
