Xoops websites are capable of rendering many different types of content, from text, formatted or not, to images, video, sound and games. There are many article managers with varying features for display and organisation, Photo albums, diary/calendars and organisers. Also real estate, advertising, and other category based content modules.

There are many modules already created for these types of content, perhaps the best way to get more insight on this is to browse the Module Repository. There are several categories here to help sift through the possibilities.
