蓝雨

打开require/imgfunc.php
找到

1. if ($ifWaterImage) {
2. if ($waterdb[type]==png) { imagecopy($sourcedb[source],$waterdb[source],$wX,$wY,0,0,$waterdb[width],$waterdb[height]); } else { imagecopymerge($sourcedb[source],$waterdb[source],$wX,$wY,0,0,$waterdb[width],$waterdb[height],$w_pct); } } else { if (strlen($w_color)!=7) return false; $R = hexdec(substr($w_color,1,2)); $G = hexdec(substr($w_color,3,2)); $B = hexdec(substr($w_color,5)); //imagestring($sourcedb[source],$w_font,$wX,$wY,$w_text,imagecolorallocate($sourcedb[source],$R,$G,$B)); if (strpos($db_waterfonts,ch/) !== false && strtoupper($GLOBALS[db_charset]) != UTF-8) { $w_text = pwConvert($w_text,UTF-8,$GLOBALS[db_charset]); } imagettftext($sourcedb[source],$w_font,0,$wX,$wY,imagecolorallocate($sourcedb[source],$R,$G,$B),$fontsfile,$w_text); }

把这段都删除了，换成下面这段

修改好了，里面中文也需要修改，中文的话需要一个中文字体库的支持，否则文字是出不来的，
宋体字库在c:/windows/font/simsun.ttc，可以把这个字库上传到论坛ftp的images/fonts/ch下
