photo, graphic, and video credits

If you use a photo, graphic, or video from the NLR Image Gallery, an NLR staff member, or a paid or external source, you must provide appropriate credit. See the entries on captions and sources for more information. NLR staff can also visit the copyrighted material page on the internal publishing site.

For Publications

When the photo or graphic source is an NLR staff member or an NLR contract photographer, use the source's name along with the NLR affiliation. Present the credit in italics, and do not use a period at the end.

Use "by" for NLR sources ("from" is for external sources).

If the photo, graphic, or video is from the Image Gallery, you must also include the image number in the credit.

Use the following format if an NLR illustration contains material from an external source.

If you use a photo or graphic from an external source (whether paid or free), use the source's name (if available) and affiliation. If there is an NLR image number, do not replace "NLR" with the source's affiliation; the image number is always an NLR reference.

Present the credit in italics, and do not use a period at the end.

Use "from" for all external sources (not "by" or "courtesy of").

If the photo, graphic, or video is included in the Image Gallery, you must also include the image number in the credit.

If the photo, graphic, or video is from iStock or a similar source, you must also include the number in the credit.

Please adhere to the following guidance when crediting graphics generated or modified by artificial intelligence (AI). This guidance applies only to technical publications, such as journal articles, conference papers, presentations, and technical reports.

For graphics created by or with the help of AI:

Graphic generated by [AI tool], [month day, year], from the prompt “[insert specific wording]”

If the prompt is very long, include the first five words (or the number of words needed to provide clarity).

Graphic generated by ChatGPT, April 7, 2025, from the prompt “river surrounded by pine trees”

Do not modify photographs or videos using AI or any other method.

If a caption is used with the photo or graphic, the credit should immediately follow it.

If the photo or graphic is used for illustrative purposes and does not include a caption, the credit should appear directly beneath the photo.

For NLR technical reports, use the “NLR_Figure_Caption” style for the caption itself, and then the “NLR_Figure_Note” for the in-text citation or other notes.

For photo collages, pages with many photos with no captions, or full-page photos, credits can be placed on the same page or a different page, wherever they best fit the design.

For document covers, credits can be placed elsewhere in the document (typically inside the front cover). Reference the page containing the photos you are crediting.

If graphics are combined to create new graphics and the original graphics are still recognizable, the original graphics must be credited. For example, if two iStock graphics are merged with NLR graphics into a collage and used on a document cover, the credit should read: Cover graphics, clockwise from bottom: iStock 12345, iStock 67891, National Laboratory of the Rockies 12345, National Laboratory of the Rockies 67891

Microsoft stock images are available through PowerPoint. You may use them in NLR publications, but do not move images out of Microsoft Office for other uses (e.g., a webpage). In general, NLR photos from the Image Gallery are recommended first, iStock second, and PowerPoint stock images last.

To credit these Microsoft stock images, use: Photo from Microsoft stock images

To credit other photos used in a PowerPoint presentation, follow the previous guidance for publication photo credits, and ensure the credit is listed somewhere on the slide itself. Do not list the photo credit in the notes section of the slide or at the end of the deck.

For the Web

For photos, graphics, and video on the web, include the credit after the caption and italicize it.

Use "from" for external sources and "by" for NLR sources. Do not use "courtesy of."

Don't include image numbers in the credit. Instead, the photo file name should include the image number so it can be easily located in the Image Gallery if needed.
