php image resize

Bananna man

Hi,

I have been trying to get a GD library image resize and file resize script going for a few days now but with little success. The scripts ive been trying to incorporate are a bit over my head, they all check file extension and have different rules for the different extensions but i just need to to run for .jpg's.

I can either resize the image when saving it in my site directory or resize them on the fly so if anyone knows a simple script for doing this please let me know. Everything ive seen so far is using about 4 or 5 functions and because its my first time using any of them im in over my head before i even get half way though the script so when something doent work i dont even know where to start looking.

Thanks

Here is an *extremely* simple resize function I wrote a few years back. I haven't rewritten it because it serves the purpose that I wrote it for - I'm not accepting input from the public or otherwise concerned about getting it perfect.

[php]function resizeAndCopy($filename, $newfilename, $new_width, $new_height) {
//Creates a resized image from $filename and copies the image to $newfilename

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

//Resample
$image_p = imagecreatetruecolor($new_width, $new_height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);

if(imagejpeg($image_p, $newfilename, 100)) return true;
else return false;
}[/php]

What this does in the script is take an uploaded photo, then creates a resized copy in a "thumbs" directory.
