## Configuration

### 1. Supabase Setup

-- Allow public read access
CREATE POLICY "Allow public read"
ON storage.objects FOR SELECT
TO anon
USING (bucket_id = 'obsidian-images');

```

### 2. Plugin Settings

1. Go to Obsidian Settings → Community plugins → Supabase Image Uploader → ⚙️
2. Enter your settings:
   - **Supabase URL**: Your project URL (e.g., `https://xxxxx.supabase.co`)

## Network and Data Disclosure

This plugin sends image files to the Supabase project that you configure. Network requests happen when you paste or drag and drop an image, delete an uploaded image from the context menu, or click **Test** in settings. The plugin does not include telemetry, ads, analytics, or background reporting to the plugin author.

## Usage

Once configured:

1. **Paste**: Copy an image to clipboard and press Ctrl/Cmd+V in your note
2. **Drag & Drop**: Drag an image file from your file explorer into the editor

During upload, you'll see a placeholder: `![Uploading image.png...]()`

After upload completes, it will be replaced with: `![](https://your-project.supabase.co/storage/v1/object/public/...)`

### Deleting Images

1. Place your cursor on an image markdown link
2. Right-click to open the context menu
3. Select "Delete from Supabase"
4. Confirm deletion in the dialog

- Ensure you're using the **anon** key, not the service_role key
- Check that your Supabase project is active

### Upload fails

- Verify the image format is supported (PNG, JPEG, GIF, WebP)
- Ensure INSERT policy is configured for the bucket

### Delete fails
- Ensure DELETE policy is configured in Supabase
