Alt-texts: the ultimate guide

I use a combination of magnification and screen reader when surfing the web. As a rule of thumb, I use magnification on larger screens and a screen reader on smaller devices.

I, like everyone else, come across many images when surfing the web. If I’m using a screen reader I depend on getting a description of the image – the alt-text – read to me.

Many times the alt-text is not helpful, often even a waste of my time because it doesn’t convey any meaning.
