1. Go to Post-> Add New and click on the add image(s) button, then upload your files. Do not add them to the general Media gallery (under Media -> Add New) or they won’t show up in your post.
2. Once you’ve uploaded your photos, copy this code in the HTML editor where you’d like to display the slideshow: [gallery slide="1"]
3. Publish your page or post and view the slideshow.
