Image Sources

How Sources Work

Sources connect your image storage (like DO Spaces or S3) to Dripimage. Each source gets a unique subdomain URL for transforms.

Example: https://your-source.dripimage.com/image.png?w=400

Response Handling

Different transforms return different response types.

Synchronous (Simple Transforms)

Resize, format, quality, halftone, etc. return immediately with a 302 redirect to the image.

HTTP/1.1 302 Found
Location: https://nyc3.digitaloceanspaces.com/trim-png/transformed/...

Asynchronous (AI/ML Transforms)

Background removal, upscale, enhance, etc. return 202 Accepted with a job ID:

{
  "status": "QUEUED",
  "jobId": "db5ed95b-7403-47e7-9627-928dc976a567",
  "pollUrl": "/api/status/db5ed95b-7403-47e7-9627-928dc976a567",
  "estimatedTime": 5000
}

Polling for Status

Poll GET /api/status/{jobId} until complete:

QUEUED Job waiting in queue

PROCESSING GPU is processing

COMPLETED Done - result.url contains the image

FAILED Error - check error.message

Completed Response

{
  "jobId": "db5ed95b-7403-47e7-9627-928dc976a567",
  "status": "COMPLETED",
  "type": "REMOVE_BG",
  "completedAt": "2025-12-17T06:31:58.000Z",
  "result": {
    "url": "https://..../transformed/abc123.png",
    "mimeType": "image/png",
    "width": 800,
    "height": 600
  }
}

JavaScript Polling Example

async function waitForTransform(jobId) {
  const pollUrl = `https://dripimage.com/api/status/${jobId}`;
  
  for (let i = 0; i < 30; i++) {
    const res = await fetch(pollUrl);
    const data = await res.json();
    
    if (data.status === 'COMPLETED') {
      return data.result.url;
    }
    if (data.status === 'FAILED') {
      throw new Error(data.error?.message);
    }
    
    await new Promise(r => setTimeout(r, 2000));
  }
  throw new Error('Timeout');
}
