Why it’s a bad idea to use text in background images
This is an awesome meme (the text at the bottom is intentionally cut off.) It nicely illustrates why including text on background images is a bad idea. Because background images get cropped as the screen changes sizes. On particularly small screens, the background image may also shrink too far to be readable. (This readability issue on small screens is a problem even for normal images with overlaid text.)
Also text in images isn’t accessible to visually impaired people, to screen readers, or to Google and other search engines. (Search engines are by far the largest “visually impaired” site visitors on the planet!)
Bottom line is whenever possible, leave text out of your images and overlay them with readable text instead.
(Note: I’m sorry I can’t find the original author of this meme so I can give them credit. I’ll update if I can find them.)
