I used below code in my projects to post the image it works fine.

    if([SLComposeViewController instanceMethodForSelector:@selector(isAvailableForServiceType)] != nil)
    {
        if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
        {

            SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];

            SLComposeViewControllerCompletionHandler myBlock = ^(SLComposeViewControllerResult result){
                if (result == SLComposeViewControllerResultCancelled) {

                    NSLog(@"Cancelled");

                } else

                {
                    NSLog(@"Done");
                }

                [controller dismissViewControllerAnimated:YES completion:Nil];
            };
            controller.completionHandler =myBlock;

            [controller setInitialText:@"Check out my Christmas Gift!"];
            [controller addImage:@"gift.jpg"];

            [self presentViewController:controller animated:YES completion:Nil];

I checked the internet and noticed a few discussion in the recent 1 or 2 days related to this issue and they seem to related to Facebook bug. So if your code post messages and images successfully to Twitter, then don't worry! you are doing correctly.

  I have resolved through open present-view controller in navigation-bar.it may help you.

 SLComposeViewController *controller = [SLComposeViewController   composeViewControllerForServiceType:SLServiceTypeFacebook];
    [controller setInitialText:shareFrom];
    [controller addImage:self.photoImageView.image];
    [controller addURL:[NSURL URLWithString:dayCareWebsite]];
    dispatch_async(dispatch_get_main_queue(), ^ {

        [self.navigationController presentViewController:controller animated:YES completion:nil];

    });
