The Picture Viewer tool is almost identical to the PictureField Viewer. The difference is that it displays pictures stored outside of ACT! whereas the other tool displays pictures already stored in ACT!. Pictures are stacked on top of one another and
you can scroll through them using VCR-like buttons. Pictures are automatically adjusted to the size of the control. It offers a number of different options like rotating, naming, etc.
Clicking a picture displays it in a popup window.
See this video on how to set it up.
