I have tried different configs to get this to work, but basically I would like to have the top pic fill the space, similiar to Flat design demo (though still want to have some of my own configs).

Is there a way to implement the same design for all galleries? In plug-in there is only one classic version to work with.

This worked, thanks!

I'm using the WP-Juicebox plugin and despite all my attempts to customise a gallery, even with PRO options are limited using this plugin, and stuggling to get the thumbSelectedFrameWidth to be the same as the thumbnail, see example here

Ideally I would like to use the Flat Design  theme, but regardless of changing my config, I can't get this to work in Wordpress.
