The biggest problem with using images over text is that it's not very search engine optimised or very good for the sites accessibility (legal requirement for businesses) - good luck having a screen-reader an image without alt text, a similar thing for the sites use of tables for non-tabular data.
It's also annoying if you try and do a ctrl+f on a page for something and it doesn't show up because it's buried in an image.
