Comment 2 for bug 1440947

The TinyMCE imagebrowser does not have access to certain strings when outside the view/blocks.php page.

It has the strings in view/blocks.php due to that page also having a filebrowser pieform present that contains the lang strings we need.

So to fix this we need to first look in lib/form/elements/filebrowser.php and within the pieform_element_filebrowser_get_headdata() at about lines 1498-1505 we see the $strings bit that we need.

We need to add that to the pieform_element_wysiwyg_get_headdata() in lib/form/elements/wysiwyg.php
