[Feature] Associate images with community and project members on CC Open source

## Problem
Currently, the profile image for each member is just a placeholder, and there’s no system in place to associate images with authors in the backend. This makes it difficult to display the correct profile images for members in line with the current vocabulary markup.

## Description
The goal is to replace the placeholder profile image with the actual image of the member, dynamically fetched based on the author’s details. This would require associating each `member.name` with a specific image in the backend.

## Alternatives
- Leave the current implementation as it is.

## Implementation

- [x] I would be interested in implementing this feature.
