I am curios to know what is the best way to display images containing text. Lately I have been using the CSS background property to display all my images and hiding the text in a span. For example the following site: http://www.caweek.org. Obviously, you can't resize the images on your screen, but If you turn off styles you will have a pure text document in your browser, apart from the occasional photograph. I have just discovered another method by where you add the image as HTML, but specify the height and width using css and making it an EM instead of PX. This enables the user to enlarge the image as they would enlarge text. This of course pixelates the image as you enlarge it, leaving an unsatisfactory but readable result. Also, if you turn styles off you still have the image displaying on the screen and you can't enlarge it. My question is what would the W3C say is best practice and the common method for people with sight difficulties to read a web page? Would they turn the styles off when they can't enlarge the image? Or would they prefer to see a blurred version when they enlarge the text? Any advice would be fantastic. Thanks in advance.
