Hey, I'm not sure if anyone ever answered your question, but here's a little
function I wrote for something similar to what you want to do and it doesn't
require GD be installed. You need to modify the top portion, I just threw
that in there to show you how it would work. $pic is the name of the image
you want to display. $largestside is the largest width/height you'll want to
be shown - So if the max height or width is supposed to only be 200, you'd
set it to that, then it scales the other side so that it displays with the
correct dimensions. This doesn't ACTUALLY resize the file, it just takes the
image and then in HTML it sets the height and width. If you need to actually
resize the file you will need GD to be installed. Hope this helps in some
way!
<?php
$pic = "image.jpg";
$dimensions = resize($pic);
echo "<img src=\"$pic\" width=\"$dimensions[0]\" height=\"$dimensions[1]\">
function resize($v_pic) {
$largestside = 120;
$size = GetImageSize ("$v_pic");
$width = $size[0];
$height = $size[1];
if ($width == $height) {
$dimensions[0] = $largestside;
$dimensions[1] = $largestside;
} elseif ($width > $height) {
$divisor = $width / $largestside;
$height = $height / $divisor;
$dimensions[1] = intval ($height);
$dimensions[0] = $largestside;
} elseif ($width < $height) {
$divisor = $height / 120;
$width = $width / $divisor;
$dimensions[0] = intval ($width);
$dimensions[1] = 120;
}
return $dimensions;
}
