How do I use short code & plugins

You’ll probably get a better response in the plugin’s support forum:

they don’t provide support for this because it’s a free plug-in and they only provide paid support.

Hi Kehau,

WordPress adds “shortcode” to the main write panel when you click the “Insert Gallery” button after uploading images into the post. If you click the HTML tab on the write panel, you will see this:

[gallery]

That is shortcode. It creates the gallery. Here is more info:

Hope that helps!
