A simple, elegant image hosting solution built on Val Town's blob storage. Upload images and get permanent, shareable URLs instantly.

This val provides a web interface for uploading images to Val Town's blob storage and generates permanent URLs that you can use anywhere - in documentation, websites, social media, or anywhere else you need to host images.

Key Features:

1. Upload: Select an image file (PNG, JPG, GIF, WebP)
2. Store: The image is saved to Val Town blob storage with a unique timestamped key
3. Share: You receive a permanent URL in the format: https://your-val.web.val.run/image/img_timestamp_filename.png
4. Use: Copy the URL and use it anywhere you need

• Images are stored in Val Town's blob storage, which is backed by Cloudflare R2
• Each upload gets a unique key: img_[timestamp]_[filename]
• Images are cached with a 1-year cache header for optimal performance
• All images in your account can be managed at: https://www.val.town/settings/blob

• File size: ~1MB per upload (Val Town form upload limitation)
• Total storage:
  • Free tier: 10MB total
  • Pro tier: 1GB total
• File types: Images only (PNG, JPG, GIF, WebP, SVG)
• For files larger than 1MB, consider uploading to another service first, then fetching server-side

This val is a remix of @stevekrouse/fileInputUploadExample, which demonstrated the basic pattern for file uploads with Hono and Val Town.

The original example showed how to set enctype="multipart/form-data" on forms - the critical step for file uploads. This remix extends that foundation with:

• Persistent blob storage instead of just echoing the file back
• Image-specific handling and content-type detection
• A polished UI with helpful user information
• Permanent URL generation for uploaded images

1. Fork this val to your own Val Town account
2. Visit your val's endpoint (it will have a URL like https://yourusername-valname.web.val.run)
3. Upload images and copy the generated URLs
4. Manage or delete uploaded images at https://www.val.town/settings/blob

Built with:

• Hono 3 - Fast web framework with JSX support
• Val Town Blob Storage - Built-in key-value storage backed by Cloudflare R2
• Standard Web APIs - FormData, File, and Blob APIs

The implementation properly handles:

• File to blob conversion
• Content-type detection from filename extensions
• URL encoding for filenames with special characters
• Cache headers for optimal CDN performance
