When it's essential for an entire image to be displayed within a container, setting the image to fit is your solution. This ensures that the image snugly aligns with the container without distortion. If the aspect ratios of the image and container differ, you can shrink the image to make it fully visible within the confines of the container.

While this approach maintains the integrity of the image, be mindful that it may leave extra empty space within the container, creating a potential visual gap in the design. This method blends precision with aesthetics, balancing the need to see the whole image while maintaining the design's overall appeal.
