Start intent to select image file from gallery...

startActivityForResult(new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI),54);

On Activity Result get file URI...

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
    if (resultCode != RESULT_CANCELED) {
        try {
            if (requestCode == 54 && resultCode != 0) {
                if (intent != null) {
                    Uri selectedImage = intent.getData();
                } else {
                    Toast.makeText(getApplicationContext(),
                            "Could not load image",
                            Toast.LENGTH_SHORT).show();
                }
            }
        } catch (Throwable e) {
            e.printStackTrace();
        }
    }
}

Get file bytes from URI...

private byte[] GetFileBytes(Uri uri)
{
    ByteArrayOutputStream bos = new ByteArrayOutputStream(200000);
    InputStream imageStream;
    try {
        imageStream = getContentResolver().openInputStream(uri);
        byte[] buffer;
        buffer = new byte[100000];
        while ((imageStream.read(buffer)) != -1) {
            bos.write(buffer);
        }
    } catch (Throwable e) {
        e.printStackTrace();
    }
    return bos.toByteArray();
}

Get MultipartEntity from byte array...

private MultipartEntity getEntity(byte[] bytes)
{
    MultipartEntity entity = new MultipartEntity();
    InputStream in = new ByteArrayInputStream(bytes);
    ContentBody bin = new InputStreamBody(in, "Image_" + c.getTimeInMillis() + ".jpg");
    entity.addPart("image_query_string_variable_name", bin);
}

MultipartEntity is a class of httpmime. You can find the JAR easily by Googling. You will need to add this jar file to your project from project properties.

Post to server...

private void PostData(MultipartEntity entity)
{
    HttpParams httpParameters = new BasicHttpParams();  
    HttpConnectionParams.setConnectionTimeout(httpParameters, 20000);
    HttpConnectionParams.setSoTimeout(httpParameters, 20000);
    DefaultHttpClient client = new DefaultHttpClient(httpParameters);

    HttpPost request = new HttpPost("http://www.you_server_url.com/someFileName.php");
    request.setEntity(entity);

    HttpResponse response = null;
    response = client.execute(request);
    BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
    StringBuffer result = new StringBuffer();
    String line = "";
    while ((line = rd.readLine()) != null) {
        result.append(line);
    }
    //
    // Process the returned result from server...
    //
}

More Edit:

byte[] fileBytes = null;
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
    if (resultCode != RESULT_CANCELED) {
        try {
            if (requestCode == 54 && resultCode != 0) {
                if (intent != null) {
                    Uri selectedImage = intent.getData();
                    fileBytes = GetFileBytes(selectedImage);
                } else {
                    fileBytes = null;
                    Toast.makeText(getApplicationContext(),
                            "Could not load image",
                            Toast.LENGTH_SHORT).show();
                }
            }
        } catch (Throwable e) {
            e.printStackTrace();
        }
    }
}

// when button is clicked...
public void onClick(View v)
{
    if(fileBytes != null)
    {
        MultipartEntity entity = getEntity(fileBytes);
        PostData(entity);
    }
}

Good Luck. :)
