Add decorations + captions on images

[patvdv]

Describe the feature you'd like

In the spirit of being "a better Confluence alternative": it would be great to have the possibility to apply various types of borders to included images. Same for defining custom captions.

Describe the benefits this would bring to existing BookStack users

Make a text with images easier to read. Resulting PDF exports would look more professional and slick as well. Captions would allow for images to be searched for (if caption text is searchable).

Can the goal of this request already be achieved via other means?

I know this has been requested before (#4872) but I think it is worthwhile to have this as a fully independent feature, i.e. customizable per image and without messing with the HTML content.

Have you searched for an existing open/closed issue?

• [X] I have searched for existing issues and none cover my fundamental request

How long have you been using BookStack?

3 months to 1 year
