Question

I have this script for displaying a slideshow for a client.

I’m looking for a quick way of making the “img” not go over a certain size.

This is my original code:

<script type="text/javascript">
$(function() {
$('#test2').crossSlide({
  speed: 15,
  fade: 1
}, [
<?php
$directory = "photos/";
$images = glob("" . $directory . "*.jpg");
$arrLength = count($images);
foreach($images as $key=>$image){
echo("{src: '$image', dir: '$quotes[$random]'}");
if($key < $arrLength - 1){  echo ", "; }
}
?>
]);
});
</script>

Prehaps I could use some sort of external file?

Link it like.. image.php?img=foo.jpg (with the max script in there?)

Any help would be great,

Thanks!

getimagesize() is a start.

if( array_product(getimagesize($image)) < 2500 ) { // Check area
  // do stuff
}

list($width, $height) = getimagesize($image);
if( $width < 500 && $height < 400 ) { // Check dimensions
    // do stuff
}

In the future, do a quick Google. PHP is a language that supports a lot out of the box. Often times, you’ll be able to find something in the docs.
