I'm having a small problem. I'm installing vbulletin settings for my banner system over at webhostdebate, but when trying to store the mime allowable types in a vbulletin setting it fails to validate an image as an image.

Code that works:

PHP Code:

if (in_array($_FILES['banner']['type'], array('image/gif', 'image/png', 'image/jpg', 'image/jpeg', 'image/bitmap'))) 


Code that fails:

PHP Code:

if (in_array($_FILES['banner']['type'], array($vbulletin->options['banner_types']))) { 


The settings banner types in vbulletin's settings is storing ['image/gif', 'image/png', 'image/jpg', 'image/jpeg', 'image/bitmap']. I'm not quite sure why this isn't working. I know the vbulletin->options variables are working properly in my script as there are many others referanced throughout. It's only in this array check that it fails. Anyone know why?
