Get Image by ID Endpoint

[AhmedFatthy1040]

Create a backend endpoint to retrieve an image by its unique ID. The endpoint should fetch the image metadata from the database and return the image file as a response.

Tasks

• Create a GET /images/{id} endpoint.
• Fetch image metadata (e.g., filename, user ID, file path) from the images table using the provided ID.
• Return the image file in the response.
• Handle cases where the image ID does not exist and return an appropriate error response (e.g., 404 Not Found).

Acceptance Criteria

• The endpoint successfully retrieves and returns an image file by its ID.
• Proper error handling for invalid or non-existent IDs.
