I have a gallery on my main page and it's great but when you view as a slideshow it only shows you half of the pics in the gallery.

How do I fix this?

First- Byron, thank you for your beautiful work. The plugin is one of the best I've seen, both GUI- and code-wise.

Michael, I came across this thread since I just ran into this issue too.

As a temporary fix (and Byron, please let me know if we aren't allowed to modify your code - and delete this post so others don't do this), I changed the value the php code (which is very cleanly written, I must say).

In bwbps-media-rss.php, edit line 28:
$aa['images_override'] = isset($_GET['images']) ? (int)$_GET['images'] : 25;

Change 25 to a number greater or equal to the number of pictures in your gallery. I used a bigger number just in case I added a few more pictures. It's working well.
