Use visuals (photos or illustrations) when it is necessary to show- what something looks like or to depict a perceptual quality such as color, texture, pattern, shape, relative size, spatial location, orientation, arrangement, or appearance
Something that is important to remember when using images is that they can be used to explain what is being described in the text. However, if the image is being used for that purpose, it must be good quality.
If the body copy is explaining the complexities of the inside of a Lilly and how it grows, the image should be clear enough to convey that information. Also when we are using images in our future content creation, I believe that we must test their quality before we officially post them to our future websites. The image could appear pixilated and therefore confusing or even useless. Images appear differently on different quality screens so when we are testing our work we should trying testing the image quality on a lower end device as well as a higher end one to maintain consistency.
