dreamwaever file management

new user question - when I put a graphic file into my images folder in the root directory in dreamweaaver, it does not show up in the dreamweaver window. finder sees it in there just fine though. The only way I can get it to show up is if I do an insert from dreamweaver, navigate to another folder location which dreamweaver can see and insert. it then pops up in the dreamweaver folder view. any thoughts on making dreamweaver see it as soon as I put it into the images folder? Thanks.
