This theme features a 3-column footer widget area on the bottom of the page:
Control what shows up here by going to Appearance >> Widgets and adding widgets of your choice into the Footer 1, Footer 2, and Footer 3 widget areas.
(Note: you must have a widget in Footer 1 in order for the entire footer area to appear.)
Footer Widgets – “Featured On” Slider
Using the Soliloquy Slider plugin, create a new slider. Keep slider dimensions small, like 85px by 85px. Copy & paste the slider shortcode into a new text widget and put it in a footer widget area. Center it by putting it in between two center HTML tags like so:
<center> [soliloquy id="43"] </center>
