[support] Module Views and Image fields

Hello, I'm trying to use Views and related Image field, however currently I'm unable to disable whatever image even after inserting some Image fields (other inserted fields are correctly displayed). I guess my usage of Image fields is simply incorrect... Could someone post or indicate path to some samples / syntax (ie. link usage) about Views and Image fields ? Note: I already installed some .jpg which are visible in my front page via classical <img src="files/ ..etc.. Many thanks. Bye, Bruno
