Is it possible to exclude certain images/thumbs from the rotating of random images on the frontpage and in subfolders? I can set the main thumb for subfolders but I can not find a way to set the main image for the frontpage and galleries itself.
I have some nude 3D renders and although over here (The Netherlands) people do not care, in other countries they don't like it to be confronted to nudity without any warning.
I use the default Effervescence+ as theme.

You can set so called albums thumbs for all albums on each album backend page. There are several options availabe either automatic or a specific image.

Yes, did find that. But I just found out that I mean the header image. I can set that in the specific theme options to once a day or not. But either option gives a random image as header image. So I am wondering if I can make the header image static. Or is is a default setting in Effervescence+ that can not be changed?

Well, it is random :-) You would have to modify the theme to use an static image. Excluding is not that simple, too.

A quick way to get what you want:

In gallery.php change line 57
printHeadingImage(getRandomImages (getThemeOption('effervescence_daily_album_image')));
to

printHeadingImage(getRandomImagesAlbum('header-album'));

where header-album is the album from which to show the random header images.
(you can of course name the album anything you like)
If you want a static header image, just put only one image in the album.

This way you can control what you want to show as header image.

Thanx Fretzl! Don't know really my way around PHP so I don't do that. But I have to do a new, clean install of ZenPhoto anyway (see my other posting).
