The Image Gallery Module is one of the most popular components not only within the Citadel CMS Framework but also on virtually every other framework on the market. It one of the reason why we put extensive effor on giving site owners various options on implementing a gallery.
From an administrative point of view, we've made it so that images can have captions, include additional descriptive content and even sorted using drag-and-drop functionality.
One of the other functions we've added is multi-upload capabilites. You can select up to 50 images in one shot and begin the upload process. The images are uploaded 5 at a time and the remaining images are "queued" and then uploaded as images are finished processing.
Not only can galleries consist of images, it can also be made of YouTube videos or files which show up as a list of documents and in a separate tab.
