Upload images and get\npermanent, shareable URLs instantly.\n\n## What This Does\n\nThis val provides a web interface for uploading images to Val Town's blob\nstorage and generates permanent URLs that you can use anywhere.\n\n**Key Features:**\n\n- Generates permanent, shareable image URLs\n- Images stored in Val Town's blob storage (powered by Cloudflare R2)\n\n## How It Works\n\n1. **Upload**: Select an image file (PNG, JPG, GIF, WebP)\n2. **Store**: The image is saved to Val Town blob storage with a unique\n timestamped key\n3. **Share**: You receive a permanent URL in the format:\n `https://your-val.web.val.run/image/img_timestamp_filename.png`\n4. **Use**: Copy the URL and use it anywhere you need\n\n## Storage Details\n\n- Images are stored in Val Town's blob storage, which is backed by Cloudflare R2\n- Each upload gets a unique key: `img_[timestamp]_[filename]`\n- Images are cached with a 1-year cache header for optimal performance\n- All images in your account can be managed at:\n https://www.val.town/settings/blob\n\n## Limitations\n\n- **File size**: ~1MB per upload (Val Town form upload limitation)\n- **Total storage**:\n - Free tier: 10MB total\n - Pro tier: 1GB total\n- **File types**: Images only (PNG, JPG, GIF, WebP, SVG)\n- For files larger than 1MB, consider uploading to another service first, then\n fetching server-side\n\n## Credits\n\nThis val is a remix of\n[@stevekrouse/fileInputUploadExample](https://www.val.town/v/stevekrouse/fileInputUploadExample),\nwhich demonstrated the basic pattern for file uploads with Hono and Val Town.\n\nThe original example showed how to set `enctype=\"multipart/form-data\"` on forms.\nThis remix extends that foundationc with:\n\n- Persistent blob storage instead of just echoing the file back\n- Permanent URL generation for uploaded images\n\n## Usage\n\n1. **Fork this val** to your own Val Town account\n2. Visit your val's endpoint (it will have a URL like\n `https://yourusername-valname.web.val.run`)\n3. Upload images and copy the generated URLs\n4.
