Alternative text check for images
=================================

The Higher Education Package contains a check for missing alternative texts on images.

If this feature is activated then the check is processed every time when a relation to an image file is added
or changed in a content element. The image relation will be disabled (2) if there is no
alternative text and the user is informed by a flash message warning (1).

.. note:: 
	| In a special case the alternative text check won't be processed.
	|
	| This case happens in the following circumstances:
	| - A record with more than one image relation is edited
	| - New relations are set in at least two image relation fields at once
	| - The alternative text check is disabled for one of those fields (see "AdministratorManual/AlternativeCheck")
	|
	| In this case the check won't be processed for any image relation. This won't occur if existing relations are
	| edited or single fields are edited.
