The term refers to a specific graphical element used on a popular social media platform. It denotes the visual representation of a post containing multiple images or videos that users can swipe through sequentially. The file format, PNG, indicates a type of image file commonly employed for web graphics due to its support for transparency and lossless compression. For example, the small symbol within the app interface that alerts users to a multi-image or multi-video post is what is being referenced.
The utilization of such a visual cue offers distinct advantages for both content creators and viewers. It enhances user experience by quickly signaling the presence of more content within a single post. This encourages engagement, increases the time spent viewing content, and allows for storytelling or showcasing multiple aspects of a product or event in a cohesive manner. Historically, the introduction of this feature marked a shift towards more dynamic and interactive content presentation on the platform.
