What is the difference between .ish and .png?

Description: The ISH file type is associated with the Image System (Hires), a format used for storing high-resolution images. Originally designed to handle detailed graphical data, ISH files are typically utilized in environments where image clarity and precision are paramount. These files can encompass a wide range of visual data, from digital art to sophisticated scientific imagery. Due to their high-resolution nature, ISH files are often larger in size compared to standard image formats, necessitating more storage space.; A PNG file is an image file stored in the Portable Network Graphic (PNG) format. It contains a bitmap of indexed colors and uses lossless compression, similar to a .GIF file but without copyright limitations. PNG files are commonly used to store graphics for web images.
