Essential Trust Badges & Icons

I'm new to web design, and I was intimidated by what sort of coding would be involved with creating clickable icons in the footer of my store for "as seen in" type links. One of the beautiful features of this app is that you can upload your own icons. In a matter of half an hour, I have placed links with logos to all the external sites for the stores we stock with around the globe, and all this in a tidy banner matched to our shop theme's text and colors. Amazing!
