Image Permission Request

To maintain consistency in the way contributors to Celsus incorporate photographs, architectural plans, or other images into articles, it is necessary to establish norms for protecting copyright associated with all images. It is not problematic to post images in the public domain or accessible through less-restrictive licensing agreements, but because many images are not in those categories, it is still necessary to at least briefly state the copyright or licensing status of each image (see Use of Images for instructions).

For many images, it will be necessary to get permission to post them in Celsus or to verify that they are freely available under a specific licensing agreement. This page presents some background about seeking permission and guidelines for documenting the images once they are posted.

Images in Celsus are accompanied by captions that contain three kinds of information:
  1. A brief description of the contents of the image
  2. A statement about copyright ownership
  3. A statement about any permissions

Images for which the copyright is held by the author of the article

Some contributors may elect to provide photographs or other images they created or for which they already hold copyright. If so, then it is possible to combine parts 2 and 3 in the caption to read something like this: The author is copyright holder for this photograph and has given permission for it to be used by Celsus.

Sample text for requests for permission to post photographs to Celsus

For images 1) not in the public domain, 2) not licensed for redistribution with attribution at other sites (like Wikimedia Commons or, or 3) owned by the contributor, contributors may request permission from libraries, architecture firms, or photographers for posting on Celsus. Contributors may phrase the request in any reasonable way, but they should contain as much of the following information as possible so the owners will understand the nature of the setting. The following should be edited to fit the circumstances.

Dear xxxx:
I am contributing an article about xxxx to Celsus, a wiki-based resource for information about aspects of library construction, renovation, and remodelling, developed within a course, "Architecture, Renovation, and Project Planning," taught by Thomas D. Walker at the University of Wisconsin - Milwaukee, School of Information studies (his contact information: I am interested in posting some photographs that illustrate the building project [renovation project, etc. -- depending on the topic] of your library and would like to seek permission to do so. The photographs I am interested in are featured on your website (list them here or provide URLs). Are you the copyright holder for the photographs? If not, could you place me in contact with the owner so that I could seek permission?

The wiki, while currently part of an educational program with provisions under the Fair Use doctrine within US Copyright law for education use of copyrighted material, has been open to the viewing public since 2010 as a moderated resource with contributing members being approved by Prof. Walker. It is set up under the provisions of a Creative Commons License (cc by-nc, Attribution-Noncommercial 3.0), which allows for use by others if attribution to the copyright holder is made (

If I may use the images, how would you like the attribution to read? Are there additional images that may be of interest to me?

I appreciate your assistance....... etc.

If a contributor contacts an institution and gains permission, it may be reflected in the caption of the image. Additionally, please summarize any correspondence in the "discussion" are associated with the relevant article (see the tabs at the top of each article) to document that permission was received and to record other information about contacts, copyright owners, and so on.
