### Step 3: Test with Thumbnailer

We used [Thumbnailer](https://github.com/minio/thumbnailer) to listen for MinIO notifications when a new JPEG file is uploaded (HTTP PUT). Triggered by a notification, Thumbnailer uploads a thumbnail of new image to MinIO server. To start with, download and install Thumbnailer.

```
git clone https://github.com/minio/thumbnailer/
npm install
```

    public void setThumbnailId_Equal(String thumbnailId) {
        setThumbnailId_Term(thumbnailId, null);
    }

    public void setThumbnailId_Equal(String thumbnailId, ConditionOptionCall<TermQueryBuilder> opLambda) {
        setThumbnailId_Term(thumbnailId, opLambda);
    }

    public void setThumbnailId_Term(String thumbnailId) {
        setThumbnailId_Term(thumbnailId, null);
    }

            String imagePath = "thumbnail/600x400.png";
            try (ImageInputStream input = ImageIO.createImageInputStream(classLoader.getResourceAsStream(imagePath))) {
                generator.saveImage(input, outputFile);
            }
            assertImageSize(outputFile, 100, 66);

            imagePath = "thumbnail/600x400.gif";
