It’s so simple you’re going to kick yourself for not using it.

To create a post/page in WordPress which becomes a gallery of images (thumbnails):

  1. Create a new page/post
  2. Upload/Attach images to the post or page using the ‘Add an Image‘ Upload/Insert feature above the content editor
  3. Add the shortcode “[ gallery ]“ anywhere in the post/page (remove the quotes and spaces)
  4. That’s it.  All images attached to that page/post will be displayed as a gallery

Some Options:

  • columns - How many columns will be used to display the gallery of images
  • size - What size should the images be presented in (“thumbnail”, “medium” and “large”)
  • orderby - Order to show the gallery

This is a great way to create simple galleries, listing of screenshots or a neat order display of images attached to a post/page.
