I'm creating some diagrams that show how images can be combined (image A + image B = image C) so I want to be able to use the images as the shapes in my diagrams to show the images come together. If I attach an image to a Confluence page, that image's default behavior when I click on it is to bring it up in a preview gallery view, where the background (page) dims down and the image gets enlarged on the center of the screen. I would love to have this same functionality when clicking on the images/shapes in a Gliffy diagram.
Right now, the closest thing I can figure out is to link to the image attachment on the page, but that opens the image in a new/separate browser window. I really need to keep the focus on the current page and just show the image in the preview mode.
