Simple image gallery needed for home page

I need a very simple plugin for a gallery on my home page that will simply cycle 4 or 5 images. No “next” links or buttons, etc., just images rotating. I tried the Dynamic Content Gallery which is about what I need but you have to specify exact image sizes for display. I need something that will pull from the media gallery and display images of various sizes. I’ve looked through many plugins but haven’t been able to find what I want. If anyone has any suggestions, it would be greatly appreciated.
