Microsoftnoahdsmith and others on the thread... Could you give us more detail on what you mean by "transparency, pictures, and colour"? Which areas of the browser are you expecting to be affected by those elements and what would be helpful/visually pleasing to see? How are you expecting to customize your browser? Which areas of the browser or functionality would you find not useful?
I suppose colours would be the most basic and most broad one - the top bar, tabs and menus (like right-click) would have a two-tone colour scheme, maybe even being able to pick the two colours, and maybe another colour for the icon lines.
A transparency option would then add to this, in being able to pick how transparent these elements became.
Pictures-wise, most of the time a picture would fill behind the menu bar and tabs, but it might be nice for some people to see the whole picture on the new tab page (though not much time is spent here).
