please dont use the frame builder to import stuff ect, just import the button through the edit image button, that frame builder gives nothing but headaches, and I for one dont even know what its there for, have never used it, and never will, but those that tend to, get problems.
and i agree with xiandi, yr best bet if yr a beginner is to read the skinstudio tutorials on the wiki, i made one especially for beginners, in laymens terms so newbies could understand it.
