Here’s my most up to date common icon links to put your html doc in the <head> section.
By now I’m pretty sure you’re gobsmacked as to how to make all those icons – ‘it’ll take forever’ he says… Fear not, I just use sweet free service Favicomatic to do all the hard work. Simply upload a high quality .png and voila, all the icons are generated in all sizes matching the above!
Enjoy, any additions let me know!
