The material this week about accessibility made me remember the late 90s and how the growth of search engines transformed many homepages. We used to make cuting edge layouts in Photoshop and include pictures on the sites. With headings mixed with photos etc. That was the only way to achive the layout we wanted in the pre css era.
But, the search engines couldn´t crawl the text in the pictures and we soon abandoned that technique. And, in the same time we became aware of the tools disabled peoples used when they visited different sites. When we removed the big shunks of pictures the sites became accessible to new groups. For instance blind people with a reading program.
