Make image_link_input_fields filterable to add buttons
|Reported by:||ryanimel||Owned by:|
This patch makes the image_link_input_fields function filterable, so that additional buttons could be added to the Link URL section when inserting an image into a post.
In my case, I want to be able to link an image to the post it belongs to. It's a weird/tiny use case, but this filter will let me use a plugin to add it myself.
