Please Help

I'm in desperate need of help here. I haven't been able to figure out the answer to my problem in the hour and half I've tried.  I want new brushes in my photoshop 7.  I've downloaded them, extracted them and they make a folder on the desktop.  But instead of all the images of the brushes included in the pack being in the folder. It's just one image to click on that says brushes and it's an ABR file.  When I click on the image photoshop starts but nothing seems to be in photoshop from the folder though. So that's my problem  I can't seem to get any of them to actually load into photoshop though.  How do I fix this?  Please help. Thanks.
