You have to extend Request and use MultipartEntityBuilder if you wanna upload your image as a file.

public class ImageUploadWithVolley extends Request {

    private MultipartEntityBuilder mBuilder = MultipartEntityBuilder.create();
    private final Response.Listener mListener;
    private final File yourImageFile;
    protected Map headers;

    public ImageUploadWithVolley(String url, ErrorListener errorListener, Listener listener, File imageFile)   {
        super(Method.POST, url, errorListener); 
        mListener = listener;
        yourImageFile = imageFile;        
        addImageEntity();
    }

    @Override
    public Map getHeaders() throws AuthFailureError {
        Map headers = super.getHeaders();
        if (headers == null
                || headers.equals(Collections.emptyMap())) {
            headers = new HashMap();
        }
        headers.put("Accept", "application/json");
        return headers;
    }

    private void addImageEntity() {
        mBuilder.addBinaryBody("give your image name", yourImageFile, ContentType.create("image/jpeg"), yourImageFile.getName());
        mBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
        mBuilder.setLaxMode().setBoundary("xx").setCharset(Charset.forName("UTF-8"));
    }

    @Override
    public String getBodyContentType()   {
        String content = mBuilder.build().getContentType().getValue();
        return content;
    }

    @Override
    public byte[] getBody() throws AuthFailureError    {
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        try {
            mBuilder.build().writeTo(bos);
        } catch (IOException e){
            VolleyLog.e("IOException writing to ByteArrayOutputStream bos, building the multipart request.");
        }        
        return bos.toByteArray();
    }

    @Override
    protected Response parseNetworkResponse(NetworkResponse response){
        T result = null;
        return Response.success(result, HttpHeaderParser.parseCacheHeaders(response));
    }

    @Override
    protected void deliverResponse(T response) {
        mListener.onResponse(response);
    }
}
