ImageSX is one of the GD functions, which requires a pre-loaded image
rather than a filename.
http://www.php.net/manual/function.imagesx.php
For example,
<?
$name = "/home/etc/etc/etc...../images/ptrs_on.gif";
$im = ImageCreateFromGif($name);
$width = ImageSX($im);
?>
One thing to note, this requires using a very old verison of GD to get gif
support. Modern versions only support jpeg and png.
Instead, you could use GetImageSize which doesn't need GD, and should
still support gif, though I've never tried it myself.
http://www.php.net/manual/function.getimagesize.php
For example,
<?
$name = "/home/etc/etc/etc...../images/ptrs_on.gif";
$size = GetImageSize($name);
echo "Image width: $size[0] <br> Image height: $size[1] <br>";
?>
