I noticed your contributions and have a few of words of advice. Please read the Manual of Style, in particular our guidelines on image sizes and videos. I will have to change the images back to the sizes I had them as previously. Also, we try to keep a constant text-to-multimedia ratio across articles - that is, not having too many images for the given amount of text in an article. This also means that we do not use galleries in articles.
Happy further editing!
