I recently encountered a neat idea but it did not register on me until it was too late (i.e. the URL was long gone from my mind and browser). What I want to do is add a series of badges on my own web page with my "credentials", which would include Stack Overflow, LinkedIn, Friend of Red Gate, CodePlex developer, SourceForge developer, and perhaps a couple others. Is there any repository of such logos/graphics/badges? Assuming not, are there any standards for sizes or shapes? Or how about anyone else's examples? And, while I am wishing, what would be especially nice is a Stack Overflow logo that included one's current rep count (i.e. it would update itself as rep changes).
