getimagesize function not working correctly

[Krik]

The following function is what I am using. For some reason it will return the recalculated image width but it will not return the recalculated image height.

But when I pull the code out of the function and use it in any place I need to change an images displayed size, it works fine.

This has me baffled, why would the exact same code work in one place but not another?

the function

function ChangeImageSize($image, $directory, $width) {

if ((isset($image)) && ($image != '')) {

	$photo = $directory . '/' . $image;
	$imagesize = getimagesize($photo);

	if ($imagesize[0]> $width) {

		$widthfrac = ($width / $imagesize[0]);

		$imagewidth = ($widthfrac * $imagesize[0]);
		$imageheight = ($widthfrac * $imagesize[1]);
	}
	else {
		$imagewidth = $imagesize[0];
		$imageheight = $imagesize[1];
	}
}
else {
	$photo = 'http://www.mysite.com/images/default.gif';
	$imagewidth = 180;
	$imageheight = 150;
}

return array($photo, $imagewidth, $imageheight);
}

a line that calls the function

list($map_image, $map_width, $map_hieght) = ($Route_Map != '') ? ChangeImageSize($Route_Map, 'maps', '520'): '';

Curious. Apart from two or three irrelevant issues I don't see anything wrong. Perhaps it's how you're using $map_width and $map_height that's at fault?

I guess I should have included that. I figured that was fairly standard but I suppose it can be done wrong.

<img src="<?php echo $map_image; ?>" width="<?php echo $map_width; ?>" height="<?php echo $map_height; ?>" />

Beyond that I started testing and if I echo the $imagesize[0] or $imagesize[1] I get the correct numbers. So it must be something with the math. Anyone see a problem with the math equations?

Just to add to my original post the height value is coming back blank (height=""), when I view the html source.

Edit:
Also the $widthfrac when echoed is a faction.

in your original post:
list($map_image, $map_width, $maphieght)
should be:
list($map_image, $map_width, $mapheight)

Now that is down right embarrassing. I thought I had checked and double checked the spelling even copied and pasted to make sure.
