• Develop a SCSS module for styling the Draggable component
• Integrate the Draggable component with the existing Photo Gallery component
• Ensure the Draggable component functions with the Photo Gallery for image reordering
• Implement logic to label the first image in the gallery as "Cover Image"
• Update the order of images in the Photo Gallery based on user-dragged changes
