Homepage default slider

Hi, I cannot figure out how to replace the default images (brick wall, flower) from the homepage and replace them with a gallery of my own. Under Appearance->Theme Options->Featured Post Slider->Slider Options, if I "Disable" the "Enable Sidebar" then the images disappear. But I can't find anywhere an option to change those images to other images. I like having the slider there, but I want my own images. What am I missing? Thanks.
