Inspired by the wonderful expressions babies make, this plugin allows you to impose speech bubbles on top of images in order to add captions. 
It does not have to be a baby or anything about kids for that matter; it works wonderfuly for images with lots of expressions.

With <a href="https://github.com/pixelgrade/pixcodes" rel="nofollow ugc">PixCodes</a> you can have a shortcode insert interface for the WordPress Classic Editor.
PixCodes is intended for Classic Editor and TinyMCE workflows. It does not add a block editor interface.
The awesome part is that you can filter any shortcode parameters or overwrite any shortcode template with your theme.
Note: this plugin does not add any style to the output of shortcodes.
We believe that shortcodes functionality should be offered by a plugin and the style should be provided by themes.
Here is a <a href="http://github.com/pixelgrade/pixcodes/blob/master/README.md" rel="nofollow ugc">detailed documentation</a> about how you can configure some plugin settings and output.

PixCodes

PixCodes offers a Classic Editor interface for inserting Pixelgrade shortcodes.
