ZIP extraction and creation of unwanted folders for them

Hi.

Is there a way to force "archive utility" to put all files from all zip's form folder to unpack all to that folder without paths and replace any duplicates or maybe rename it? In WinRAR that action i can perform without any effort from my side, on Mac i cannot find any app to do that. There is Stuffit, but this app is corny.

Example: I have 30 different zip with pictures, but in some of them are duplicates (same pictures) and what i need is to Archive utility (or other app) to extract all zips into current folder without folders around them, into root of that folder and replace all duplicates with one, so i get one copy of picture instead of 30...

cheers
