How to implement Icon, Title and url link to colintree

This is what I tried

Using Components
Colintree list view Extension

What I want
Icon I can get icon from desired URL link and I can add to Colin tree. I want to know it is possible to get high pixel icon and save as cache?
Title how can i get title from desired url and add to colintree?
Ads I know browser app not eligible for Ads. Please reconfirm for this App.
