Final answer:
Multiple image file formats are needed for various reasons, such as specific characteristics, compatibility, and flexibility in image manipulation.
Step-by-step explanation:
There are several reasons why we need to have multiple image file formats. One reason is that different file formats have different characteristics and are suitable for different purposes. For example, JPEG (Joint Photographic Experts Group) format is commonly used for digital photos because it can display millions of colors and is compressed to create smaller file sizes without significant loss in quality. Another reason is that different applications and devices may support different file formats, so having multiple formats ensures compatibility across different platforms. Lastly, having multiple formats allows for flexibility in image manipulation and editing, as different formats may offer different features and capabilities.
