You can use the Theme image mask on the lower right to select the region of the image to use. However, that theme image is used in such a way on the finished page that how much of it you see depends on the size of the viewport. Rather than try to describe it, just make your browser window narrower and wider, and you'll see the effect.
Choosing the Turntable view under Projector > Cover page > Title > Type might be a better choice.
The skin doesn't provide a direct way to get rid of the image entirely, and tinkering with the CSS tends to produce some nasty layout problems (like a big blank space where the theme image should be - not really what you want). I'll post back if I get lucky.
I'm not sure whether that's better or worse. I think I would be more inclined to find a theme image that works better, then use it everywhere - add it to a folder, exclude it, and drag it to the Theme image box on the right.
I'm happy with the theme image. It's the image below it that I'd like to be able to... Have it gone completely
That is the Theme image. What's above that is the logo you have added. The code I have posted should make it disappear, while leaving your logo image alone. Try it.
Is there a way to trick things which you suggested doing something like putting my desired image in the first folder then not displaying it as part of the folder?
Yes, and this is a standard trick in jAlbum, used a lot. Say there's an image you want to use as the theme image, but you don't want it to actually appear in the album anywhere else. So, no slide image for it, it's not in any thumbnail layout, etc.
Add the image to the project (at the top level, for example).
Exclude the image - don't delete it, just choose it and click the Exclude icon at the top (looks like a "do not enter" traffic sign).
Now drag that image to the Theme image box on the lower right.
You can do the same thing inside each folder, too.
ETA: You can, of course, crop that image outside of jAlbum before you add it to the project. But since it's going to be displayed across almost the entire width of the browser, make sure it's a large image. Otherwise it will get blurry. So, at least 1500px wide and 500px tall.
I applied the code to the correct place, with the #s but I see no change in the results. I've gotten use to it as it makes the landing page have the same look as when you click into a sub-folder so it's not so much of an issue to me now.
Thank you for your help on this topic and my other thread.
