Hi all -

Trying to work out some problems with my thumbnail script.

here is my script:

PHP Code:
//thumbnail width and height
$t_width 250;
$t_height 200;

//get file information            
list($width$height$type) = getimagesize("$dir/$fname/$file");
$ratio_orig $width/$height;

        if (
$t_width/$t_height $ratio_orig) {
$t_width $t_height $ratio_orig;
                } else {
$t_height $t_width/$ratio_orig;
$thumb imagecreatetruecolor($t_width$t_height);
$src imagecreatefromjpeg("$dir/$fname/$file");

I'm getting a number of errors that are giving me a headache, let me start with two:

1) $thumb = imagecreatetruecolor() [function.imagecreatetruecolor]: Invalid image dimensions
I'm getting great thumbanails for both portrait and landscape - any idea as to why this warning is occuring?

2) imagejpeg() expects parameter 1 to be resource, boolean given.
I suspect this has to do with my first warning but not sure how to move forward.

Thanks in advance - I'm new to this area of php and any help would be appreciated.
