I have searched and maybe I missed this. How can I set the header image to not be random on the main page? I found it for each gallery but I can't find it for the main Gallery page.

The header for both the gallery (index.php) and the albums (album.php) is created by the call on printHeadingImage(). You will need to pass it a static image rather than a call to getRandomImages()

i tried this out and failed miserably.
i had this:
and changed it to this:
and the whole page didn't load.

the header.png image is in the same dir as the gallery.php...seems like the thing to do. any thoughts on what i messed up?

athat might just be that the function parameter is an image object. You have passed a string.

I guess I'm just dopey. I can't get my head around what I'd put in there as a function. I looked through the functions guide but frankly 90% of it is over my head.
