For a better SEO, but also not to share your local files names, especially for pictures / images medias, and avoid sharing bad names like 11-finalresult.png in the example, but having a nicer ms-excel-2013-how-to-make-a-table-look-good-resize-columns-to-fit-content.png instead, a good and simple solution is to use the plugin Media File Renamer.
