Help! PHP / GD thumbnail creation

[oast]

Would have edited previous message, but option was not there as it was a "Quick Reply"

Any way, I played with this and moved the imageCreateFromJPEG function above the image sizing functions. Also used full paths.

So try this:

function do_thumbs( $fn ){
  $img_src    = "/home/user/rep_pics/large/".$fn;

  $med_height = 250;
  $med_width  = 200;
  $med_dest   = "/home/user/rep_pics/medium/".$fn;

  $sml_height = 125;
  $sml_width  = 100;
  $sml_dest   = "/home/user/rep_pics/small/".$fn;

$med_source_handle = imageCreateFromJPEG($img_src);
if(!$med_source_handle){ die("couldn't get the source handle - $img_src"); }
$sml_source_handle = imageCreateFromJPEG($img_src);
if(!$sml_source_handle){ die("couldn't get the source handle - $img_src"); }

  $src_height = ImageSY($med_source_handle);
  $src_width  = ImageSX($med_source_handle);
  $med_image  = imageCreateTrueColor( $med_width, $med_height );
  imageCopyResampled($med_image, $med_source_handle, 0, 0, 0, 0, $med_width, $med_height, $src_width, $src_height );
  imageJPEG($med_image, $med_dest, 90);
  chmod($img_src, 0777);
  imageDestroy($med_image);
  imageDestroy($med_source_handle);

  $src_height = ImageSY($sml_source_handle);
  $src_width  = ImageSX($sml_source_handle);
  $sml_image  = imageCreateTrueColor( $sml_width, $sml_height );
  imageCopyResampled($sml_image, $sml_source_handle, 0, 0, 0, 0, $sml_width, $sml_height, $src_width, $src_height );
  imageJPEG($sml_image, $sml_dest, 90);
  chmod($img_src, 0777);
  imageDestroy($sml_image);
  imageDestroy($sml_source_handle);
}

Ya I got it figured out finally. My host had error messages turned off so it was a pain in the ass to figure out.. I finally got GD set up right on my local test bed and it all started making sense . Here's the 'finished' code if anyone ever needs it.

function do_thumbs( $fn ){
  $img_src    = "../rep_pics/large/$fn";

  $med_height = 250;
  $med_width  = 200;
  $med_dest   = "../rep_pics/medium/".$fn;

  $sml_height = 125;
  $sml_width  = 100;
  $sml_dest   = "../rep_pics/small/".$fn;

  $source_handle = imageCreateFromJPEG($img_src);
  $src_height    = ImageSY($source_handle);
  $src_width     = ImageSX($source_handle);

  $med_image  = imageCreateTrueColor( $med_width, $med_height );
  imageCopyResampled($med_image, $source_handle, 0, 0, 0, 0, $med_width, $med_height, $src_width, $src_height );
  imageJPEG($med_image, $med_dest, 90);
  chmod($med_dest, 0777);
  imageDestroy($med_image);
  
  $sml_image  = imageCreateTrueColor( $sml_width, $sml_height );
  imageCopyResampled($sml_image, $source_handle, 0, 0, 0, 0, $sml_width, $sml_height, $src_width, $src_height );
  imageJPEG($sml_image, $sml_dest, 90);
  chmod($sml_dest, 0777);
  imageDestroy($sml_image);
}
