Create A WordPress Image Gallery

A gallery will display a set of thumbnail images attached to a particular post or page. If you upload images using the Add an Image button while editing/creating the post or page, they will be attached automatically. If you upload images directly to the media library from Media -> Add New, you will need to attach them to a post or page before they will appear in a gallery.

1. Open a post or page for editing. If it is a new post or page, make sure to add a title and save it at least once before trying to insert a gallery.

2. Click the Add an Image button.

3. Select files to upload and then click the Save all changes button. You should be taken to the Gallery tab next.

4. Customize the settings. (I used 5 columns for the layout above.)
   Click Insert gallery.
