I am a wedding photographer, so many of my customer galleries end up with hundreds images in them, but the built-in slideshow feature seems to top out at 201. When I start a slideshow of a gallery and pull up the bottom menu, only the first 200 images are avaiable to click on. If I want to view any images after #201, I have to just wait until the show gets there on its own.

Is there any way to add another image bar thingy to the pop-up menu? I just want my customers to be able to easily view the later images in a slideshow.

My second question: Can I change the default background color of the slideshow to a different shade? For instance, could it start as white or gray rather than black?

Thanks.

Not a this point. I believe you will be able to customize the sideshow in the future.
