PostcardViewer

This is the tag you have to adjust:

[pcviewer id="GALLERY ID" width="WIDTH" height="HEIGHT" link="LINK (optional)"]

Here you can see the inline version:

[pcviewer id="2" width="500" height="650"]

and here as a link:

[pcviewer id="2" width="500" height="650" link="Click me..."]
Click me...
