This is a very barebones plugin, it aims to do one thing well and nothing else. There are no fancy extra features. Just insert [postslideshow] on your post content where you want the slideshow to appear and you’re good to go. All the pictures of the current post will be included in the slideshow.
The dimensions of the gallery can be configured in options menu.
