How do I upload a new version of an existing picture, replacing the old one?
• A: Use the upload button and press the correct button (replace existing file): This will use the same file name, and the old picture will be replaced. This way the comments (which are tightly connected to the filename) will also be transfered to the new picture. If you zap the old pictures, and upload new versions (with new names) the comments so far will be gone forever.
