Struggling with image upload from my iOS to my PHP server

The code below is used to upload image to a remote server, but for a certain reason it does NOT work for me. When I enter, for example to this page and I use the php form to upload image, it works with no problem. So, concerning the PHP part, there is no single problem and everything is working.

The Question :

What's wrong with that ?

        NSData *imageData = UIImageJPEGRepresentation(self.imageViewer.image, 90);
        NSString *urlString = @"http://example.com/post_image.php";
           [request setHTTPMethod:@"POST"];
                request = [[NSMutableURLRequest alloc] init];
        [request setURL:[NSURL URLWithString:urlString]];
        [request setHTTPMethod:@"POST"];           
        NSString *boundary = @"---------------------------14737809831466499882746641449";
        NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];
        [request addValue:contentType forHTTPHeaderField:@"Content-Type"];           
        NSMutableData *body = [NSMutableData data];
        [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
        [body appendData:[@"Content-Disposition: form-data; name=\"image\"; filename=\".jpg\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
        [body appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
        [body appendData:[NSData dataWithData:imageData]];
        [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
        [request setHTTPBody:body];            
        NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
        returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
        NSString *picture = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
        NSLog(@"uploaded picture: %@", picture);

Change the mime type to match what you're actually sending (image/jpeg).

Delete one of these duplicate lines:

NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

(and probably at least log the error parameter...)
