Serve images with the article file.

[NurElHuda]

If we want to add an image to an article, we have to host it in a third party place then reference it from there.

It would be benefcial if the node.js server serve the images linked to the articel as well, and does not require the use of third party to do so.

Currently we don't have an effective way to handle images. adding them to the repository will make it grow out of hands as there is no limit to the amount of articles, projects, and images in each article. hosting them on a dedicated service is much more effective. maybe we will consider this in future releases. thank you for the suggestion.
