When you are writing an article for Wikipedia, you must include a picture to provide evidence to the reader about the business, or the theme you are writing for. It creates awareness in the readers, as they follow the picture and look for the related images to get a clear understanding of the topic. The picture can be of the logo or organization board as explained by Wiki Page Creation. However, for the images as well you have to mention the source, if you are the owner of the picture make sure you have copyrights of it. What do you think about including a picture in your article?
