Good catch. That is ironic on so many levels. I mean there is even a section on "UX: Bandwidth"... Maybe the author should brush up on image compression best

Good catch. That is ironic on so many levels. I mean there is even a section on "UX: Bandwidth"... Maybe the author should brush up on image compression best practices and consider adding a subsection on images and other media. EDIT: Realized my previous wording was probably a bit too harsh considering the author is still relatively new to web development.
