Improve Notification Box Styling for Downloading External Links

Description: Currently, when a user tries to download an image using an external image link, a notification box appears. The design of this notification box could be improved to better align with the overall UI and enhance the user experience.

Proposed Solution:

• Redesign the notification box to be more visually appealing and user-friendly.
• Ensure the design is consistent with the overall theme of the platform.
• Make the notification more noticeable while maintaining a clean and minimalistic design.
