A picture is not always worth a thousand words. Maybe some people find pictures or videos helpful, but we don’t. We deplore instructions that don’t have enough clear text to permit us to install and use a product. As an example, we purchased a bike light as a safety measure, because a lot of motorists simply don’t see the cyclists because they aren’t as large as cars. But the bike light is still sitting around because the pictures are worse than nothing. Perhaps the problem is that the pictures are created by “right-brained” artists and we are a “left-brained” engineer type. We also suspect that some manufacturers of products they sell to customers in different countries want to economize on packaging and/or instruction sheets that otherwise would need to be printed in multiple languages.
