I’m not blind, but if carefully tailored pictures can be useful, certainly for charts and graphs.

See https://en.wikipedia.org/wiki/Tactile_graphic, https://data.europa.eu/apps/data-visualisation-guide/tactile...

Given the low information density of tactile graphics (eyes can resolve finer details than fingers, so braille letters are large, dithering isn’t useful in small areas, etc), it’s even more important to know what you want to show in an image, though, so that you can leave out the rest.
