ARRRRGH!
Just got up, feel like I have a hangover which is not really fair because I didnt drink so dont deserve one.
It really is screwed up, you pull an all nighter and when you get up you look at the code you produced and it just isnt your best work... and the question pops up, why bother?
Sorry, a bit of a rant in the middle of my coffee ;)
just wanted to thank all of you who replied, I really appreciate it... was way out in the zonked zone when I wrote and asked for help and the fact that some of you actually read that long ass bit of code.... AND responded shows that there IS hope for humanity, coz there are a lot of good folk still out there. Ok, a bit dramatic... but still not thinking too straight, gotta refill my cup!
Thanks and tcare ppl!

Wow, that's one ugly ass script!
Basically, to answer your question: use the SECOND parameter to
imagejpeg/imagepng/imagewhatever. The 2nd parameter takes a string which
denotes the path to the file it should store it in.
This should work a bit better for you:
<?php
function resizeImage($origPath, $destPath=null, $outputType='png') {
// dimensions of the thumbnail to be created
// we will retain aspect-ratio later on
$destHeight = 90; // pixels
$destWidth = 90; // pixels
$origImage = file_get_contents($origPath);
// reading original failed
if(false === $origImage) {
return false;
}
$origStream = imagecreatefromstring($origImage);
// unsupported image type provided
if(false === $origStream) {
return false;
}
// calculate thumbnail size, retaining aspect ratio
$origHeight = imagesy($origStream);
$origWidth = imagesx($origStream);
if( ($origHeight/$origWidth) > ($destHeight/$destWidth) ) {
$destWidth = ($destHeight/$origHeight)*$destWidth;
} else {
$destHeight = ($destWidth/$origWidth)*$destHeight;
}
$destStream = imagecreatetruecolor($destWidth, $destHeight);
imagecopyresampled($destStream, $origStream, 0, 0, 0, 0, $destWidth,
$destHeight, $origWidth, $origHeight);
// write the image
switch($outputType) {
case 'png':
imagepng($destStream, $destPath);
break;
case 'jpg':
case 'jpeg':
imagejpeg($destStream, $destPath);
break;
case 'gif':
imagegif($destStream, $destPath);
break;
}
// free memory
imagedestroy($destStream);
imagedestroy($origStream);
return true;
}
This function is slightly easier for you to use. pass in the original
path to the image, 2nd param determines if it should be saved anywhere
or directly sent to output (by passing null. Be sure to set the correct
header first though)
