[Plugin: PWA php] Short code question, regarding number of images on page

Short Code question. I’m using Version 0.9.4. I’m using this short code on a post:

[pwaplusphp album="SignsWithHumor" images_per_page="2" image_size="800" thumbnail_size="125"]

I took this from the actual plugin page with short code examples on it;

[pwaplusphp album=”some_album” images_per_page=”20″ image_size=”800″ thumbnail_size=”32″]

Display photos from some_album only with different settings for image size, thumbnail size and images per page. (v0.9.3+ only)

Page, Post

But the post is showing all the images in the album (at this time it is 4). I just want to see 2.

What I am doing is calling this post into the footer, and I want this post to show 2 photos from the album, and I am assuming it will show the latest 2. (?)

Am I thinking the ‘images_per_page’ does something it doesn’t ??
Thanks! ??
