你总是花很多时间去做一些按纽吧,去设计一个好的按纽背景全部用它吧!
  文字可以随意更换!
  
  
  Header( "Content-type: image/gif");
  if(!isset($s)) $s=11;
  //times.tif可以是你喜欢的任何字体
  $size = imagettfbbox($s,0, "/fonts/TIMES.TTF",$text);
  //设定长宽
  $dx = abs($size[2]-$size[0]);
  $dy = abs($size[5]-$size[3]);
  $xpad=9;
  $ypad=9;
  $im = imagecreate($dx+$xpad,$dy+$ypad);
  //设定R,G,B
  $blue = ImageColorAllocate($im, 0x2c,0x6D,0xAF);
  $black = ImageColorAllocate($im, 0,0,0);
  $white = ImageColorAllocate($im, 255,255,255);
  //画图
  ImageRectangle($im,0,0,$dx+$xpad-1,$dy+$ypad-1,$black);
  ImageRectangle($im,0,0,$dx+$xpad,$dy+$ypad,$white);
  ImageTTFText($im, $s, 0, (int)($xpad/2)+1, $dy+(int)($ypad/2), $black, "/fonts/TIMES.TTF", $text);
  ImageTTFText($im, $s, 0, (int)($xpad/2), $dy+(int)($ypad/2)-1, $white, "/fonts/TIMES.TTF", $text);
  ImageGif($im);
  ImageDestroy($im);
  ?>
  
  重要的是你不能在这段代码中加入任何的HTML标记,尤其不允许在 and ?> 当中加入!
  
  调用时写下面的代码:

  s是图片的大小 text是图片的文字
