Images and Text Do Not Mix
This PowerPoint presentation on cars
(we know it’s about cars because an introductory slide consists of the word "CARS" in huge, garish orange-and-blue letters) puts all of its images in the background (after applying a little tasteful fading), with paragraphs of text
overlaid on them. This accomplishes the difficult feat of making the images hard to look at and
the text hard to read. Perfect—a lose-lose situation!
The presenter could have consolidated the text in one part of the image, using the image’s horizontal guiding lines; but that didn’t happen, so the slide manages to look sloppy as well as unreadable. Bonus points for misspelling “carburetor.”
