If you dumped the icons directly into the toplevel of /usr/share/icons, 
that's most definitely NOT compliant with the icon theme spec, and that'll 
explain why the tool complained about it. Icons in /usr/share/icons MUST be 
installed according to the icon theme spec. /usr/share/pixmaps is the 
directory where you can just dump an image file, but that practice is indeed 
deprecated (the main reason being that that simplistic approach cannot 
support multiple sizes; it also doesn't allow icon themes to supply themed 
versions of the icons).
