Why is ini_set ('memory_limit') not working?

Question

I am doing a file resize function and when I use very high resolution images I get this fatal error:

PHP Fatal error:  Allowed memory size of 33554432 bytes exhausted (tried to
 allocate 8884 bytes) in /path/resizer.php on line 35

(resizer.php is the resizer class) Then when I use ini_set ('memory_limit', '64MB'),

.. before the whole block: if (isset ($ _ FILES ....)) ... And I get this fatal error:

 PHP Fatal error:  Allowed memory size of 262144 bytes exhausted (tried to 
allocate 8884 bytes) in path/resizerenter code here.php on line 35

Note that the allocated memory decreased when I requested an increase. Please let me know if you know what is wrong. Many thanks

check php.ini setting: memory_limit

Maybe more than 64M already. If you can

   ini_set('memory_limit', '128M'); or 256...

Operations on large images can ruin huge memory!
