Ask where you got the image from! Did you donate to the Egami forum to get the image? If not, you won't get any support there – I was banned because I answered the admin's question about "where I got the image for my Vu+4K" and told him I wasn't donating anything to download a test image.

And if you don't even know how to install an open image on a Dream, then you should probably leave it alone.
