JPEG jumble: the week’s best reader-submitted photos
From architecture and animals to automotives and landscapes, these are the Photo of the Day winners.

A race car zips down the track to a child’s delight. The sun’s last golden tendrils cling to a cloudy sky. A horse and its rider share a tender moment. For this week’s Photo of the Day challenge, we asked readers to show us what they most love to photograph, and the results are a delightful mélange of subjects.
Want to be featured in a future Photo of the Day gallery? Weekly themes are posted Sundays. To enter, you can upload your submissions to our Flickr pool, tag them on Instagram and Twitter, or join/upload them to our Photos of the Day Facebook group.

Best buds

Lucia Williams touchingly captures the trust and bond between a horse and its rider—something crucial when performing stunts.
Shapes

Chris For’s use of B&W draws the eye to the structure’s distinct geometric patterns and the landscape’s fading light. There’s an air of drama and loneliness that pervades the frame.
Cannonball

Jeff Dennis makes a splash with a split-second frame from the 2022 Canada Games. The lines in this image add to its compelling allure.
Sunset serenity

It’s the last warmth and glow of a sunset, a daily event that always brings a little melancholy. Debra Clare’s image displays the wonder and awe of standing under a vast sky in the dying light.
Zoom zoom

Angie Muzeni-Corino’s picture captures the energy of a day at the racetrack, buffered by the innocent curiosity of a child peering between the chain-link fence, hoping for a glimpse of the action.
Red-winged Fairywren

A fluffy Fairywren precariously balances on a flower’s stem, the florals’ deep red petals a perfect punctuation mark on the scene shot by Dalida Innes.
