[PATCH] upload image fix

[gregmac]

I have two sites with safe mode on where images were not able to be uploaded, giving the following errors:

Warning: imagejpeg(): Unable to access /..../wp-content/test.thumbnail.jpg in /..../wp-admin/admin-functions.php on line 761

Warning: imagejpeg(): Invalid filename '/..../wp-content/test.thumbnail.jpg' in /..../wp-admin/admin-functions.php on line 761

Warning: Cannot modify header information - headers already sent by (output started at /..../wp-admin/admin-functions.php:761) in /..../wp-admin/inline-uploading.php on line 101

I was unable to determine the percise cause of this, but creating the thumbnail image before writing to it seemed to work (therefore this is likely a bug upstream in GD or PHP somewhere). The following patch is a workaround:

                        if ($type[2] == 1) {

No action in over a year and questionable validity due to the recent upload changes.
