Klaus,
Images posted to the community go through moderation before being widely viewable. I looked into the images from your previous posts and discovered it was my own error that deleted the images. I guess I hadn't had enough coffee yet and accidentally hit delete when I meant to hit approve. My apologies. 🙂
