Decrease in value

I have 2 sizes $w and $h being sent via a GET variable. Via a getimagesize method i'm getting the original size of a image. I want to then take down the image in size one pizel at a time till either the $w or $h are equal or smaller than the original.

list($width, $height) = getimagesize($filename);

$newheight = $height;
$newwidth = $width;

do {
	$newwidth--;
	$newheight--;
} while ($newwidth == $w Or $newheight == $h);

When I echo this out, I get my original size, my new max size and then the original less one pixel meaning it's looped only once. Why?

($newwidth == $w Or $newheight == $h)

Where do [font=monospace]$w[/font] and [font=monospace]$h[/font] come from? Regardless, even if this is true once, the moment you decrease both [font=monospace]$newwidth[/font] and [font=monospace]$newheight[/font] the only way it will still be true is if [font=monospace]$newwidth[/font] was originally equal to [font=monospace]$w+1[/font] or [font=monospace]$newheight[/font] was originally equal to [font=monospace]$h+1[/font]. And it certainly won't be true after another decrease.

I think you need to think about the logic of what you're trying to do some more. For example, the approach you're describing won't preserve an image's aspect ratio unless it happens to be a perfect square.
