Photos are still images shared on Instagram, either individually or in multi-image posts called carousels1. Instagram selects photos for Feed and Explore using signals such as whom people follow and what they have liked or interacted with, allowing photos to reach both followers and people who do not follow the creator23. Creators can adjust brightness, contrast and filter strength, and add custom alternative text that describes photos for people using screen readers45. Mosseri said in February 2025 that Instagram does not automatically reduce photos’ and carousels’ visibility compared with Reels; his January 2025 guidance listed adding audio and avoiding watermarks among the requirements for recommendations to 67. In April 2026, Instagram for Creators defined original photo content as work creators wholly make themselves or that reflects their unique perspective, including third-party material meaningfully changed with additions such as informative text or creative graphics8.

How photos appear in Feed and Explore

Instagram considers recent photo posts from followed accounts and potentially interesting accounts a person does not follow when assembling Feed, alongside other posts and ads2. Its Feed choices take account of whom someone follows and what they have recently liked or interacted with2. Explore can find photos through connections between people's interests: Instagram's example starts with someone liking a chef's photographs, then considers other accounts enjoyed by people who also like that chef3. Mosseri said in February 2025 that Instagram does not automatically reduce the visibility of photos and carousels compared with Reels6. Mosseri explained that Reels tend to attract more engagement because they combine moving pictures and sound, although some accounts find that photos and carousels perform better than Reels6. Mosseri recommended audio on photos and carousels in September 2024 because it could help engagement9. In January 2025, Mosseri listed adding audio among the requirements for content to be considered for recommendations to , emphasizing its importance for photos and carousels7. For photos to be considered for recommendations to people who do not follow the account, Mosseri's January 2025 guidance also specified no watermarks7.

Creating and managing photo posts

Editing tools and AI images

Instagram's photo-editing controls include brightness, contrast, saturation and warmth; Meta's Newsroom and Mosseri also announced additional photo filters in November 2023, ranging from subtle color changes to more expressive styles41011. Creators can control how strongly a filter is applied to a photo4. Mosseri described artificial-intelligence image-editing tools as coming soon in the United States in September 2023, then announced testing and rollout over the following weeks in September 2024 for changes such as adding or removing objects and replacing backgrounds1213. Generating a new image is a different use: Instagram's December 2024 announcement described creating imagined versions of someone from supplied photos in a chat, while Mosseri's September announcement described AI-generated selfies becoming available across Feed, Stories and Profile1314. In October 2025, Mosseri also pointed creators to in the Stories creation process as a way to change a photo's appearance15.

Accessible descriptions and downloadable copies

Instagram's automatic alternative text provides spoken descriptions of photos for people using screen readers in Feed, Explore and Profile, using technology that recognizes objects in an image5. Custom alternative text lets the person uploading a photo supply a richer description for a screen reader to read5. To save copies of uploaded photos, Meta's Newsroom said Download Your Information and Access Your Information were centralized in , where people could download uploaded Facebook and Instagram photos together or choose the accounts separately16.

Photo storytelling, reach and earnings

Multi-photo storytelling

Mosseri suggested trying carousels because a sequence can offer a richer experience and give one post multiple chances to appear in followers' feeds17. In his July 2024 photographer spotlight, he praised Reuben's use of carousels and occasional video within them as ways to encourage engagement18. His April 2024 spotlight on Johannes also highlighted turning Stories from a Tokyo trip into a Feed post so viewers could follow the trip as a sequence19.

The photo-view bonus test

The Instagram bonus announced by Meta's Newsroom and Mosseri in November 2023 covered both single-image posts and carousels for selected creators in the United States, South Korea and Japan120. Invited creators could activate the bonus and earn based on photo views during the bonus period, provided their content passed 1. The announcement said selected creators would be invited to test it until the end of that year and called it the year-end bonus in South Korea and Japan, rather than describing a generally available ongoing program1.

Originality and sensitive-photo visibility

For photo posts, Instagram for Creators' April 2026 definition of covers work creators wholly make themselves or that reflects their unique perspective8. For photo posts using third-party material, Instagram for Creators says meaningful changes can qualify as original, such as creative graphics or text that adds information rather than merely describing what is already shown8. Instagram's Help Center says photos flagged by the community as sensitive may have their visibility limited, and sensitive or graphic images may carry a warning before someone views them in Feed or on a profile21. The Help Center says and the corresponding content setting do not apply to posts carrying these warnings21.
