    if (resource) 
    { 
     //----- here i am getting the resource ID ------- 
     [[NSUserDefaults standardUserDefaults]setObject:resource forKey:@"GETRESOURCE"]; 
     [[NSUserDefaults standardUserDefaults]synchronize];

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{ 



    CGFloat maxCompression = 0.1f; 

    UIImage * getimage =[self imageWithImage:[info objectForKey:UIImagePickerControllerOriginalImage]]; 
    NSData *imageData = UIImageJPEGRepresentation(getimage, maxCompression); 

    NSDate *currDate = [NSDate date]; 
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc]init]; 
    [dateFormatter setDateFormat:@"YYYY-MM-dd HH:mm:ss Z"]; 
    NSString *dateString = [dateFormatter stringFromDate:currDate]; 


    //--- convert image to string ----- 

    NSString* imageString = [imageData base64EncodedStringWithOptions:0]; 
    //---- new change -- 

    imageString = [imageString stringByAppendingString:@".IMAGE"]; 

    //------------- 

    if ([imageString length] > 0) 
    { 
     [dbHandler insertChatHistory:imageString imageData:nil receiveType:2 mediaType:1 receiverName:titleName date:dateString]; 

     NSXMLElement *body = [NSXMLElement elementWithName:@"body"]; 
     [body setStringValue:imageString]; 

     NSXMLElement *message = [NSXMLElement elementWithName:@"message"]; 
     [message addAttributeWithName:@"type" stringValue:@"chat"]; 
     [message addAttributeWithName:@"to" stringValue:receiver]; //--- jenish --- 
     [message addChild:body]; 
     [self.xmppStream sendElement:message]; 

     [messageType addObject:@"1"]; 
     [messageArray addObject:[NSDictionary dictionaryWithObject:imageString forKey:@"Text"]]; 
     [self.timestamps addObject:[NSDate date]]; 

    } 

    [self finishSend]; 
    [JSMessageSoundEffect playMessageSentSound]; 
    [self scrollToBottomAnimated:YES]; 
    [self reloadMessages]; 

    [self dismissViewControllerAnimated:YES completion:NULL];
