You would want to make that HTTP request using POST and append to the body of the request the binary data of your photo.

To do so:

NSURL * requestUrl = [NSURL URLWithString:...];
NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:requestUrl];

request.HTTPMethod = @"POST";
request.HTTPBody = [NSData dataWithBytes:xData length:xDataLen];    
[request setValue:[NSString stringWithFormat:@"%d",xDataLen] forHTTPHeaderField:@"Content-Length"];
[request setValue:@"your/contenttype" forHTTPHeaderField:@"Content-Type"];
[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

You should change xData, xDataLen and "your/contentype" with your real data.
