Android : Upload image via PHP

I need to upload image to server, but I am not good in PHP.

So can anyone help me with image.php ?

And it will be great if it bring me link to the uploaded image, like "/uploads/imgname.jpg". Something like that i guess:

$flag['link']=$link;    
print(json_encode($flag));

This is my sending part:

private class ImageUploader extends AsyncTask<Void, Void, String> {

    @Override
    protected String doInBackground(Void... params) {
        // TODO Auto-generated method stub
        String result = "";

        // Client-side HTTP transport library
        HttpClient httpClient = new DefaultHttpClient();

        // using POST method
        HttpPost httpPostRequest = new HttpPost("http://10.0.2.2:4492/image.php");
        try {

            // creating a file body consisting of the file that we want to
            // send to the server
            File imageFile = new File(filePath);
            FileBody bin = new FileBody(imageFile);

            MultipartEntityBuilder multiPartEntityBuilder = MultipartEntityBuilder.create();
            multiPartEntityBuilder.addPart("images[1]", bin);
            httpPostRequest.setEntity(multiPartEntityBuilder.build());

            // Execute POST request to the given URL
            HttpResponse httpResponse = null;
            httpResponse = httpClient.execute(httpPostRequest);

            // receive response as inputStream
            InputStream inputStream = null;
            inputStream = httpResponse.getEntity().getContent();

            if (inputStream != null)
                result = convertInputStreamToString(inputStream);
            else
                result = "Did not work!";
            return result;
        } catch (Exception e) {

            return null;
        }

    }
