I have a custom module with a content field (WYSIWYG editor)
When I select the insert image button, the following popup appears. For some reason the ‘browse’ button at the side of the Image URL has disappeared. Can someone point me in the right direction to get the image icon back? (what block/controller etc)
What is required when adding the full featured WYSIWYG editor to a custom magento module?

This is my form field element within Form.php (block)
$fieldset->addField('post_content', 'editor', array(
'name' => 'post_content',
'label' => Mage::helper('faqs')->__('Answer'),
'title' => Mage::helper('faqs')->__('Answer'),
'style' => 'width:700px; height:500px;',
'wysiwyg' => true,
));
Thank you.

I managed to sort this by adding some configuration options to the field,
Add the following code above the addField() of your WYSIWYG,
Once you’ve added the code, you need to add another param to the addField called ‘config’ calling your $configSettings variable.
