[Commentor] LC-328 Ian Jacobs [Comment] * Please provide more rationale for this one, which I did not understand when I first read it. Something like this might help: "Because mobile devices have limited processing capabilities, make available small versions of images rather than require resizing after delivery." [Working Group decision] The text already reads: "Resizing images at the server [...] reduces amount of data transferred and the amount of processing the client has to carry out to scale the image." [Commentor reply] 
yes
