Something like this would work:

<?php


//////////////////
// change these //
//////////////////


$file = './test.jpg';
$padding = 10;
$color = array (255, 255, 255);


/////////////////////////////
// these can stay the same //
/////////////////////////////


$size = @getimagesize ($file);

$blank = @imagecreatetruecolor ($size[0], $size[1] + $padding);
$original = @imagecreatefromjpeg ($file);

$col = @imagecolorallocate ($blank, $color[0], $color[1], $color[2]);
@imagefilledrectangle ($blank, 0, 0, $size[0], $size[1] + $padding, $col);

@imagecopyresized ($blank, $original, 0, 0, 0, 0, $size[0], $size[1], $size[0], $size[1]);

header ('Content-type: image/jpeg');
@imagejpeg ($blank);

@imagedestroy ($blank);
@imagedestroy ($original);


?>

Just customize the three variables and I think that should cover it... Although I only tested it with one image, so if you find some bugs please let me know. 🙂

Very thanks brandtj, Cool Script 🙂

I think that you should not use the @ error suppression operator in this context. Why do you use it? It will only cause confusion by causing errors to be totally ignored.

Sorry I've just always been a fan of custom errors rather than PHP errors... I guess it's just habit to put them in even when I'm not putting in any error checking haha.

You can still do custom errors even without using @

Remember that you should probably have a suitable error handler which logs errors somewhere helpful and/or carries out other reasonable actions before showing the user a pretty (but nonspecific) error page.
