What is the difference of icon veneration between various Christian confessions? What is the difference of icon veneration between various Christian confessions?

It will be interesting to hear view of point from representative of each confession, and finally create comparative table of this act.

It seems, that most interesting and fuzzy difference is between east orthodox and catholic Christians. Furthermore, it seems that official doctrines of each confession can differ from how Christians of that confession really do veneration of the icons.
From catholic perspective, an icon is a symbol, nothing more. you do not pray to it, but ask for the intersession (of the depicted individual perhaps) for you. 

@Andremoniy, I think there is already a lot of good summaries of this on the web, you can probably compile a smaller summary, and ask people to verify if it seems accurate to them.
