Photographs

Every photograph on this site comes from Wikimedia Commons and is used under the license its author chose, either a Creative Commons license or a public domain release. Each entry gives what the picture shows, the author as named on Commons, the license with a link to its official deed, and a link to the original file page, where the full-size original and its history can be seen.

All photos were cropped, resized and converted to WebP for faster loading. Where a maker's name or logo was visible on a product, it was blurred so that no brand appears on these pages; those photos are marked below. No other changes were made to what the photos show. The number in each entry matches the picture's number in this site's image list.

Illustrations

Illustrations 1 to 3 and 5 to 8 were drawn for this site and carry the caption "Illustration" wherever they appear. They show a ceiling fan turning counterclockwise over a bed (1), an outdoor air conditioner unit shimmering in desert heat (2), a cooling center room set up with chairs, cots and water (3), a cutaway of a rooftop evaporative cooler and its wet pads (5), a two-story house with a hot upstairs under a baking attic (6), a desert house being cooled with night air (7), and foil under attic rafters reflecting the roof's heat (8). They contain no text and no brand names.

Figure cards

The figure cards on each article and section page, the small almanac-style panels of numbers, were drawn for this site from the cited figures. Every number on a card also appears in that page's text, next to a link to the primary source it came from, and the source line at the bottom of each card names those sources.

Using these pictures

The photographs remain under their authors' licenses, so anyone reusing one should follow the license terms on its Commons file page, not this page. Questions about a specific photo's license are best checked against that file page, which is the authoritative record. For how the rest of the site is put together, see about Swelter Almanac.
