Making it Easier for Users to Add Pictures to an Image Slider

Hello,

I love the image slider that is pre-installed with upfront, but I'm trying to make a site that is very easy for writers to add images to sliders within their posts. There doesn't appear to be an easy way for users to add images to the slider without entering the upfront interface.

Is there a way to do this that I'm not seeing?

Thanks,

Ryan
