There are many accessibility issues with using a screenshot of text instead of text directly:

- displaying a white background image of text when I'm using dark mode;

- using a small font to a user with a visual imparement or on a high DPI display;

- using a colour scheme with low contrast, or colours that are indistinguishable for people with a form of colour blindness;

- using a font that is difficult to read for someone with dislexia;

- etc.

And others have mentioned not being able to search for the text within the image, or select/highlight the text (useful for copying a function name, link, or term in the text, or for keeping track of where you are when reading).
