Hi, I've installed Pro properly in my WordPress plugins folder and the Juicebox logo does not appear in the galleries. I've listed two options in the correct Manage Galleries Gallery ID/Pro Options with the correct syntax and one per line. The two options are:
galleryTitlePosition="NONE"
galleryTitleHAlign="RIGHT"

They don't show in the source code. I changed the gallery height to see if that would change and it did -- just to make sure the info was not cached.

-- thanks!
