Remove Fullscreen Button
If you would like to remove the "Fullscreen" button from the lightbox, use the following code.
Note: The "Fullscreen" button is not shown in Chrome because the browser default settings has fullscreen viewing disabled. This is not a SmugMug bug. The Fullscreen icon will only be shown, if it was enabled, in Firefox, Safari, IE, etc.
Add the following CSS code to your theme's Advanced CSS settings:
/* Remove the full-screen button */
