Image Link
In one sentence
A hyperlink wrapped around an image instead of text, so the clickable element itself carries no visible words.
Analogy Mental model
A QR code printed on a poster. It gets you somewhere, but it explains nothing until you scan it.
In practice What you actually do
Because the image carries no text signal, the alt attribute does the work of an anchor. Write alt text that describes the destination in plain language, and treat every sitewide logo link as a chance to reinforce the brand rather than to insert keywords.
Where people get burned Pitfalls
A logo linking home with alt text reading logo-final-v3 dot png wastes the most repeated link on your site. It should read as the brand name, or simply as home.
