It may be useful when you need to attach many images to the same post. This plugin divides your wordpress gallery into several dynamic pages. It can works in two ways: modifying the [gallery] shortcode output or do not affect it when you use [pgallery] shortcode instead. The following settings of the plugin are available: number of images per page, hide or show edit attachment link, and the same as in standard wordpress gallery: number of columns, preview size, link from preview, tags of items, captions and previews, sort order, exclude some attachments.
Note that if you set the plugin to [pgallery] mode then you may use both [gallery] and [pgallery] shortcodes in your blog. For instanse, you may apply another plugin to replace standard [gallery] output. When activating first, the Paged Gallery plugin is set to [gallery] mode.
