Displaying pictures within icons is a technique used to enhance the visual appeal and provide additional information or context to icons. It involves incorporating a small image or graphic into the design of an icon, allowing users to quickly identify and understand its purpose or function.
This technique offers several benefits. It can improve the user experience by making icons more intuitive and easier to interpret, especially for complex or abstract concepts. Additionally, it can enhance the visual appeal of an interface, adding a touch of personality and creativity. Furthermore, it can help save space, as a picture within an icon can convey more information than text alone.
