This patch works with The Pony Gallery ML 2.4.1. and The Image Magic (check your config:Joomla Administrator->System->system Info->PHP Info->ImageMagick support)

Problem:  "Fatal error: Allowed memory size ..." while uploading new photo. "Save mode' is on and you can't increase PHP memory limit with ini_set('memory_limit', '50M');

Solution: Try to use Image Magic instead of GD. This patch replaces the original resize function with version that works with IM.

Installation: 

1) Backup your files.

2) Download and unzip archive.

3) Copy file common.ponygallery.php into directory /administrtor/components/pony_gallery/
