I've been using this for double-click image mount:

Once it's mounted, you can use my Tray utility to unmount just by selecting the drive letter radio button and clicking the Open Button. Or you can just right click the mounted image in Explorer and click Eject.
My Tray app is on the front page of my site:

afa copy to folder ordinary explorer drag & drop works fine.
One caution about these image mounters, if you try to access with multi-threaded app such as a multi-threaded video converter or multiple instances of a video converter they can often hang. Still the emulator is a nice free utility. Once installed I forgot about it. I had to dig it out to remember the name of it.
