Just a tip if you are using these...
In the mod, you can
1) do not hack the files var_styles_1.cgi etc (in non-cgi directory). Instead, assign these buttons directly from the cp.
2) or, replace the button file names in the original text with these filenames when hacking the vars_styles_1.cgi file.
(explanation: The CP assignments actually write to these cgi files. So either you assign in the CP and leave the program to write to the cgi files, or as the hack does, hardcode the button file names into the cgi and and let the program read directly from it. All this is because I had designed 30 odd buttons before I got the hack from mystormynight and then I was too lazy to change the names back to what he used in his mod
