FTP download a picture show again? Unfit to do so, the phone's memory and storage will not stand, if concurrent access to a lot of words, FTP services can not stand.
LS can achieve another idea: Http to show through.
Ideas are as follows:
1 built HTTP service, the picture file resources placed under the HTTP service path for HTTP Client Access;
2 files added in the layout ImageView controls;
3 In the AndroidManifest.xml file to add network access:

4 In MainActivity add the following code:

 
ImageView imgView; 

@ Override 
protected void onCreate (Bundle savedInstanceState) {
super.onCreate (savedInstanceState); 
setContentView (R.layout.activity_main); 

imgView = (ImageView) findViewById (R.id.imgView); 
imgView.setImageBitmap (getBitMap ("http://XXXX.com/your.jpg")); 
} 

public Bitmap getBitMap (String imgUrl) {
URL urlImg = null; 
Bitmap bmp = null; 
try {
urlImg = new URL (imgUrl); 
} Catch (MalformedURLException e) {
e.printStackTrace (); 
} 
try {
HttpURLConnection conn = (HttpURLConnection) urlImg 
. OpenConnection (); 
conn.setDoInput (true); 
conn.connect (); 
InputStream is = conn.getInputStream (); 
bmp = BitmapFactory.decodeStream (is); 
is.close (); 
} Catch (IOException e) {
} 
return bmp; 
}
