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.
Check the "click-enlarge" checkbox in the back-end to allow users to click to show the full-size image.
With TYPO3, controlling the behavior of images is simple. Editors with no knowledge of HTML can easily manage links, popups, captions, alignment, and more.
