The appearance of promotional edits
Please do not add images to articles when the use of that image is likely to be perceived at promotional without discussing it first. See WP:NOTPROMO and Talk:Turbomolecular pump. davidwr/ (talk)/(contribs)  22:34, 22 October 2015 (UTC) Hello davidwr, thanks, got your message and in the future will discuss the adding of images prior to their publication. I have seen your comments with regards to an image on this very page that contains the brand name of a turbomolecular pump manufacturer. We need to be consistent with the Wikipedia fair standards, equal for all, therefore I would highly support you in removing the image as the brand name is perfectly visible on the photo and is for sure perceived as promotional.
