Regarding your question about deletion, regular user are not able to delete pages or files. Only Administrators are able to do this. If you want to be an admin, learn about Wikipedia's rules, make many (generally in excess of 1000) productive edits, and go through a Request for Adminship. Until then, see Wikipedia:Deletion policy for how to request the deletion of items. Happy editing! timrem 03:48, 1 March 2007 (UTC)[reply]

Let's see. If you created these images yourself and wish to release them into the public domain, you can add ((pd-self)) to each image page. If you want them deleted, you can add ((d|uploader request)) to each page. If you wanted to do something different, feel free to contact me again on my talk page and explain further what you wanted. Good luck! timrem 20:02, 1 March 2007 (UTC)[reply]
