1.4.5 Images of Text, states at the beginning, "If the technologies being

Also this will apply only to images of text for example text snips
not for general images like photographs.

> Yes, technologies being used here are the technologies used to creat the
web like HTML, CSS, Javascript/Jquery, etc for creating web pagbes and
Office documents, spread sheets, presentations, and Accrobat etc to creat
web content.
