With TYPO3, controlling the behavior of images is simple. Editors with no knowledge of HTML can easily manage links, popups, captions, alignment, and more.

Images Linked to Internal and External Pages
Each image can be linked using the link field in the back-end. Multiple links can be added by separating each link with a comma. Values entered into the link field can be page id, a URL, or an e-mail address.
About These Pages
The pages in this section of the introduction package demonstrate the various content elements available to editors in the TYPO3 backend interface, and their appearance in the front-end.
The layout and behavior of these examples are configurable via TypoScript and, of course, CSS.
