-(void)imagePickerController:(UIImagePickerController*)picker didFinishPickingMediaWithInfo:(NSDictionary*)info
{
NSData * dt = UIImageJPEGRepresentation([info objectForKey:@"UIImagePickerControllerOriginalImage"],1);
NSURL *url = [NSURL URLWithString:@"http://www.mysite.com/myfolder"];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setDelegate:self];
[request setData:dt withFileName:@"myphoto.jpg" andContentType:@"image/jpeg" forKey:@"photo"];
[request startAsynchronous];
}
