Creating a pop up window
Would like to create a pop up window for a photo gallery. Thought I could do it by creating a new page in site builder (and I can), but it is a full page and I would like the pop up window to only be about 650x200. Tried to search for answers here, but not finding anything. Thanks in advance! The page I'm working on is linked here...http://www.sfabrushfiretrucks.com/lgb... - when you click on the first picture, "Rule", you can see a new window opens up with the gallery but is full page.
