A blog post from AgilePartners describes how upcoming web applications like Fluxiom achieve the dynamic image resizing effects illustrated in their promotional material. It turns out to be very simple (Javascript modifies the CSS image size property) yet the effect is really cool. True 'image resizing' is not employed, large images are downloaded to the browser and then it is left up to the browser's own display engine to perform the dynamic resizing. In a high bandwidth environment this does not matter but for people stuck in 56k modem land it is just one more nail in the coffin for their enjoyable Internet experience. There is almost a need now for web developers to be able to distinguish between low and high bandwidth users in the same way browser or Javascript detection is employed.
