Sending image from C# program to PHP webpage for display -

i'm new c#, , i'm working piece of code:

//take snapshot left camera , save current directory "snapshot.png"             case key.z:                 int left = camleft.device.lenscorrection1;                 camleft.device.lenscorrection1 = 0;                 thread.sleep(150);                 bitmapsource bmpsource = camleft.device.bitmapsource bitmapsource;                 memorystream ms = new memorystream();                 bitmapencoder encoder = new pngbitmapencoder();                 encoder.frames.add(bitmapframe.create(bmpsource));                 encoder.save(ms);                 ms.seek(0, seekorigin.begin);                  system.drawing.bitmap bitmap = new system.drawing.bitmap(ms);                 string filepath = environment.currentdirectory;                 string filename = system.io.path.combine(filepath, @"snapshot.png");                 bitmap.save(filename, imageformat.png);                 bitmap.dispose();                 camleft.device.lenscorrection1 = left;                 break; 

this code developed camera that, on button press, takes snapshot , stores png file. alone works--but i'm trying have take image data , automatically send php webpage automatically takes in data , displays image (bypassing having store in mysql server). want work single button press--from snapshot being taken, uploading webpage viewed.

so here's above code looks new, problematic/not working code inserted in between space in above code:

//take snapshot left camera , save current directory "snapshot.png"             case key.z:                 int left = camleft.device.lenscorrection1;                 camleft.device.lenscorrection1 = 0;                 thread.sleep(150);                 bitmapsource bmpsource = camleft.device.bitmapsource bitmapsource;                 memorystream ms = new memorystream();                 bitmapencoder encoder = new pngbitmapencoder();                 encoder.frames.add(bitmapframe.create(bmpsource));                 encoder.save(ms);                 ms.seek(0, seekorigin.begin);                  byte[] imagebytes = ms.toarray();                 string base64 = imagetobase64(imagebytes);                 string base64encoded = httputility.urlencode(base64);                 webclient client = new webclient();                 client.uploadstring("www.thisismydesiredurl.com", base64encoded);                                     system.drawing.bitmap bitmap = new system.drawing.bitmap(ms);                 string filepath = environment.currentdirectory;                 string filename = system.io.path.combine(filepath, @"snapshot.png");                 bitmap.save(filename, imageformat.png);                 bitmap.dispose();                 camleft.device.lenscorrection1 = left;                 break; 

the imagetobase64 method converts image base64, implied:

public string imagetobase64(byte[] imagebytes)     {             // convert byte[] base64 string             string base64string = convert.tobase64string(imagebytes);             return base64string;                 } 

the additional code meant take image, convert bytes, convert base64, upload string via post method php page ready receive data. php page has following code that's meant decode , display image:

<?php $data = $_post['base64encoded']; $decodedata = urldecode($data); $rawdata = base64_decode($decodedata); $source = imagecreatefromstring($rawdata); ?>   <img src= "<?php echo $source ?>" alt="test"/> 

but it's not working--no image displayed, know page up. missing?

i'm open easier/alternate solutions may not know about. want have image automatically viewable on definite url single button press--that's all.

edit: answer provided below "works", broken image on website--so seems image being uploaded , sent website, it's not being encoded/decoded correctly. can't seem figure out why, either. thoughts?

the way doing it, it's never going work. when make http post, server side scripting meant handle , give output. however, same output not visible when visit script outside of http post request.

what need post data image upload script. script should save file on server , display it.

for example:

c#

using system; using system.collections.generic; using system.linq; using system.text; using system.io; using system.net; using system.drawing; using system.collections.specialized;  namespace consoleapplication1 {     class program     {         static void main(string[] args)         {             // load image             system.drawing.image myimage = getimage("http://personal.psu.edu/tao5048/jpg.jpg");              // convert base64 encoded string             string base64image = imagetobase64(myimage, system.drawing.imaging.imageformat.jpeg);              // post image upload handler             using (webclient client = new webclient())             {                 byte[] response = client.uploadvalues("http://yoursite.com/test.php", new namevaluecollection()                 {                     { "myimagedata", base64image }                 });                  console.writeline("server said: " + system.text.encoding.default.getstring(response));             }              console.readkey();         }          static system.drawing.image getimage(string filepath)         {             webclient l_webclient = new webclient();             byte[] l_imagebytes = l_webclient.downloaddata(filepath);             memorystream l_stream = new memorystream(l_imagebytes);             return image.fromstream(l_stream);         }          static string imagetobase64(system.drawing.image image, system.drawing.imaging.imageformat format)         {             using (memorystream ms = new memorystream())             {                 // convert image byte[]                 image.save(ms, format);                 byte[] imagebytes = ms.toarray();                  // convert byte[] base64 string                 string base64string = convert.tobase64string(imagebytes);                 return base64string;             }         }     } } 

php test.php

<?php   // handle post if (count($_post)) {     // save image file     $imagedata = base64_decode($_post['myimagedata']);      // write image file     $h = fopen('test.jpg', 'w');     fwrite($h, $imagedata);     fclose($h);      // success     exit('image uploaded.'); }  // display image if (file_exists('test.jpg')) {     echo '<img src="test.jpg" />'; } else {     echo "image not uploaded yet."; }  ?>

output of c# app is:

after image uploaded, if visit http://yoursite.com/test.php (for example) in browser, see (i.e. uploaded image c#, saved on server, being served back):

hope helps.
