These are articles which have been discovered to have missing diagrams/pictures/illustrations/etc. In most cases the article will refer directly to the missing image.
I would be of great help if you could create new images for these articles and then take them off the list.
If you find another article with a missing image or diagram you can add it to this category by writing [[Category:Articles needing diagrams]] to the end of the article.
