Feature: Course Cover Image Support

Currently, courses in Planet do not have a visual element that represents them, which makes it harder for users to quickly identify and differentiate courses.

This feature introduces a new field called cover for courses, allowing the association of a representative image.

Goal

Add a new cover field to courses in Planet to:

• Improve visual identification of courses.
• Provide a consistent and user-friendly course presentation.
• Enable better integration with client applications such as myPlanet.

Cover Image Specifications

The cover image must comply with the following requirements:

• Aspect ratio: 1:1 (square)
• Minimum resolution: 512 × 512 px
• Maximum resolution: 1024 × 1024 px
• Format: JPG / JPEG
• Purpose: Visual representation of the course

---

Current Limitation

• Courses currently have no associated image or visual identifier.
• Course listings rely only on text, which affects usability and discoverability.
• There is no standardized way to attach or validate course images.

---

Proposed Solution

1. Add a new optional field cover to the course model.
2. Allow uploading or assigning a cover image when creating or editing a course.
3. Validate the uploaded image against the defined specifications:
   • Aspect ratio
   • Resolution limits
   • File format
4. Store and expose the cover field via the API for client consumption.

Benefits

• Enhances user experience and course discoverability.
• Provides a consistent visual standard across all courses.
• Prepares the backend for improved UI presentation in client apps.
• Aligns course data with modern content platforms.

Technical Considerations

• Define storage strategy for cover images (local, CDN, or object storage).
• Consider fallback behavior when a course has no cover image.
• Ensure backward compatibility for existing courses.
