Alt text may be thought of as just the text you see when an image doesn’t work.. Not very important you think as skip insert Alt text prompt. Here are some reasons to think other wise:
• Alt text is used by “screen reader” software so that a person who is listening to the content of a web page (for instance, a person who is blind) can interact with this element.
• Google ranks websites higher if a site accommodate users with disabilities
• Keyword in the descriptions will help your SEO eg. LK Design: This is an image.
• Alternative Text is shown if an image fails, or is slow in uploading a description
