Original, what should I do if Imperial CMS7.5 cannot save images without suffix?

Modify e/class/functions.php RepImg function

        $zz1="/\<(img|IMG) (.*?)(src|SRC)=('|\"|\\\\\"|)(.+?)(\.jpg|\.JPG|\.gif|\.GIF|\.png|\.PNG|\.bmp|\.BMP|\.jpeg|\.JPEG)(.*?)>/is";
        $text=preg_replace($zz1,"<\\1 \\2\\3=\\4".$exp1."\\5\\6".$exp2."\\7>",$text);

Change to

        $zz1="/\<(img|IMG) (.*?)(src|SRC)=('|\"|\\\\\"|)(.*?)('|\"|\\\\\"|)(.*?)>/is";
        $text=preg_replace($zz1,"<\\1 \\2\\3=\\4".$exp1."\\5".$exp2."\\6\\7>",$text);

Modify e/class/connect.php DoTranUrl function

       $r[filetype]=GetFiletype($url);

Add another line after

        if ((strlen($r[filetype]) !==4 ) OR (strlen($r[filetype]) !==5 )) $r[filetype]=".jpg";

After modification, the original normal use will not be affected, that is, pictures in ordinary form and pictures without extension can be correctly saved remotely.
