Sometimes in a theme, it becomes necessary to have both a max width [b]and[/b] max height with different variables. Zenphoto doesn't currently allow that, But I modified the script to do just that. (Please excuse the hack-ish nature of this, I'm not a very good php guy):
In config.php, change lines 60 - 63 from:
`
$conf['image_size'] = 595;
// If this is set to true, then the longest side of the image will be $image_size.
// Otherwise, the width of the image will be $image_size.
$conf['image_use_longest_side'] = true;
`
to:
`
$conf['width_image_size'] = 595;
// set this to the maximum height you want an image to be
//
$conf['height_image_size'] = 500;
`
and in i.php, change line 13 from:
`
$image_use_longest_side = zp_conf('image_use_longest_side');
`
to:
`
$height_image_size = zp_conf('height_image_size');
`
and lines 68 -75 from:
`
} else {
if ($image_use_longest_side && $h > $w) {
$newh = $size;
$neww = round(($w / $h) * $size);
} else {
$neww = $size;
$newh = round(($h / $w) * $size);
}`
to:
`
} else {
$tempw = $size;
$temph = round(($h / $w) * $size);
if ($temph > $height_image_size) {
$newh = $height_image_size;
$neww = round(($tempw / $temph) * $height_image_size);} else {
$newh=$temph;
$neww=$tempw;
}
`
it works, but I'm sure someone can make the code look a little more pretty ;-)
