This is a shortcode to create animated popup windows. It supports text, images and links. Create dynamic foot notes, explore digressions, extend your posts. 
Check out <a href="http://www.marcusmeditations.info/discussion/" rel="nofollow ugc">the live demo.</a> 
example: 
[info_popup pop_title=”Headline at the Top of the Window” message=”This is the main text” pop_image=”example.jpg”]clickable text in your post or page.[/info_pop]
Here’s a template you can copy and paste:
[info_popup pop_title=’PASTE THE WINDOW’S HEADLINE HERE’ message=’PASTE THE MAIN TEXT HERE’ pop_image=’example.jpg’]THIS TEXT WILL SHOW AS BEING CLICKABLE IN YOUR POST BECAUSE IT’S WRAPPED IN THE SHORTCODE[/info_popup]
Example:
I’m using (open anchor tag here) in the example because otherwise it will render as a live anchor tag on this page (the wordpress plugin repository page you’re visiting right now).
[info_popup pop_title=”Here’s a Headline!” message=”Here’s a message! And here is a (open anchor tag here) link to the onion.(close anchor tag here)” pop_image=”example.jpg”]Click me![/info_popup]
Use the code above in any page or post.
To set colors and animation for the popups, go to Appearance->info popup options.

The purpose of this plugin is to allow users to create one or more modal dialog(s) / pop-up window(s) that will appear when a user visits their site. The number of times that these can load is configurable. They can load content from external sites or custom HTML code into the dialog. This plugin can be used to invite people to register to a newsletter, respond to a survey, or simply welcome come to a site upon their first visit.
You can try it out in a temporary copy of WordPress <a href="https://demo.tastewp.com/modal-dialog" rel="nofollow ugc">here</a>.

Modal Dialog

The others either didn't work or caused massive JavaScript problems, breaking other plugins.

This plugin worked the best.
