A minimal image hosting service that displays the last 4 uploaded images.

The application is fully functional with images displaying correctly on the home page.

• /add - Upload form for new images (no navigation links to this page)
• Automatic cleanup: images are deleted when there are 4 newer images
• Mobile and desktop friendly
• No frontend JavaScript required
• File size limit: 10MB per image
• Supports common image formats (JPEG, PNG, GIF, WebP)

• Built with Hono framework
• Uses SQLite for metadata storage (filename, content type, file size, upload date)
• Uses Val Town Blob storage for image files (stored as base64)
• Images are automatically cleaned up when more than 4 are uploaded
• Responsive design with CSS Grid and Flexbox
• Server-side rendering with no client-side JavaScript
• Upload functionality available but not linked from the UI
