With the Concrete5 Popup block, you can make links to other pages on your site open with a dialog box. What makes this solution really cool is that it loads your existing concrete5 areas & blocks! Great for popup photo-enlargement, contact forms, faqs, etc.
Here are the options:
Example 1: a standard link, with a class name of "popupLink"
Example 3: here i'm using the ProPhoto image gallery block to display a collection of images (note that it also works great in filmstrip mode), having those link to a page with the File-Details block, and then applying the popup to those links, by using a "CSS Selector" rule of ".proPhotoWrap a".
Example 4: using the concrete5 popup block with an html image map.
