I've just downloaded from the WP repository and installed your plugin.
I've got an error while activating it. my WP is 3.4.2 italian with Tiny mce Advanced installed.I've tried to activate with and without TMCE Advanced.
Warning: Creating default object from empty value in X:\.....\wp-content\plugins\eg-attachments\lib\eg-plugin.inc.php on line 804
I've missed somthing?
Best regards. Giorgio.
