Catholics why the image Worship?

If one WORSHIPS an Idol then one believes that IDOL can do what GOD can do. Catholics don't worship images or idols, they honor GOD, because they believe he is the only GOD, The pray to Mary and the saints to INTERCEDE for them like a child going to a mother if they are afraid the father won't grant their request. Even though I am not a Catholic, I do understand and see this to be the truth.
