Ah, I forgot the \n newline character you're adding as well. That would
require you to chop off two character instead of one :-)
Here's the adjusted script:
<snip>
$dir = "images";
$d = opendir($dir);
$out = "
var tinyMCEImageList = new Array(\n";
while(false != ($entry = readdir($d))) {
if(preg_match("/(.jpg|.gif|.png)$/", $entry) != false) {
$out .= "['{$entry}', '{$dir}/{$entry}'],\n";
}
}
$out = substr($out, 0, strlen($out) - 2); // MY LINE
$out .= ");\n";
</snip>
hth,
Yves

I tried all this, all i want is something line this
var tinyMCEImageList = new Array(
['1_h_1.gif', 'images/1_h_1.gif'],
['1_h_1.gif', 'images/1_h_1.gif']
);
But this what i got
var tinyMCEImageList = new Array(
['1_h_1.gif', 'images/1_h_1.gif'],
['1_h_1.gif', 'images/1_h_1.gif'],
);
Remember the last commad on the last element. please show some example code
