Imagine how annoying this is for a display reader customer, especially when you may have cefixime dosage, cefixime dosage, cefixime dosage, cefixime dosage, cefixime dosage, cefixime dosage. ten of them in a line. A display reader could say, “Image, spacer image” ten circumstances in a row (screen viewers usually say the word, “Image”, before reading out its ALT text) – now that isn’t helpful!

The same applies for any other text message embedded within an image. The ALT text should merely repeat, word-for-word, the text secured within that image.

(Unless the font getting used is especially exceptional it’s often unnecessary to introduce text inside images – advanced navigation and track record effects can now be achieved with CSS. )

Company logo
