Description:
------------
in ext/gd.c ext/gd_ctx.c  
(PG(safe_mode) && !php_checkuid(fn, "rb+",  
CHECKUID_CHECK_FILE_AND_DIR)))  
should be :  
(PG(safe_mode) && !php_checkuid(fn, "wb+",  
CHECKUID_CHECK_FILE_AND_DIR)))  
because with "rb+" it's impossible to create a new file  
with imagepng,imagejpeg, etc ....  
("r" change mode from CHECKUID_CHECK_FILE_AND_DIR to  
CHECKUID_DISALLOW_FILE_NOT_EXISTS).

This is the same issue covered in bug #35060 (though you do suggest a potential fix).  sniper@php.net claims this is a documentation problem, not a bug.
 [2005-11-02 22:28 UTC] sniper@php.net 
Fixed in HEAD and PHP_5_1 branches.
 [2005-11-03 21:21 UTC] sniper@php.net 
This bug has been fixed in CVS.

will be in the next snapshot. You can grab the snapshot at

Thank you for the report, and for helping us make PHP better.
