Hi there, wget -r is very useful to slurp and archive entire web sites, I use it all the time when working with other web designers remotely. However, images declared in CSS rules are ignored by the robot if they are not seen elsewhere in the HTML pages. Therefore, to mirror the site properly, such images must be fetched manually with separate commands after poking into each individual CSS file -- a cumbersome and error- prone process. As web designers increasingly rely on background images in CSS to cleanly separate presentation from content, wget ought to accomodate this feature.
Happy Friday the 13th, JFG
