 There is currently no proper way to hook into image captions.

 Image captions are stored into the excerpt of attachments posts but when
 the caption is retrieved it doesn't go threw any specific filter.

 I think it would be nice to have a `add_filter ( 'image_caption',
 'your_filter' );` or something similar.

 This was already discussed here : [https://wordpress.org/ideas/topic/add-
 image-caption-hook#post-28710]

 Captions are used by multiple themes and plugins. They are fully supported
 and showed in twenty-fifteen so I think we should be able to properly
 hook/filter them.
