Template:Alternative text missing
This template is used to mark articles which are missing the alternative text for images (see WP:ALT). The template is based on Template:Coord missing which uses an identical structure to flag those articles needing geographical coordinates added.
Usage
{{Alt text missing|optionalpar1|optionalpar2|optionalpar3}}
Parameters
If no parameters are present then the article will be added to Category:Unclassified articles missing image alternative text.
If parameters are present then the article with be added to Category:optionalpar articles missing image alternative text. That category may need to be created as this template only creates the link – it does not create the category.
The categories should be hidden categories using Template:Hidden category. To view hidden categories, one needs to activate them at Preferences → Appearance → Advanced options → 
Show hidden categories.
Removal of template
The template should be removed when the alternative text has been added to the article.
