follow the directions and you should be good to go. You only need to download the
HDWall_v0.27b.zip ..unzip onto ur computer, run the hdwall.exe file and it'll lead the way. make sure you change the profile in the program to "WM6.5-TouchFLO v2.1 - No Compression - All Tabs" and do the regedit afterward. : Disable the default wallpaper for the Home Tab in Manila v2.1 & HTC Sense by removing the data found at HKCU\Software\HTC\Manila\HomeBackgroundPath (don't delete the key, just the valuedata)
This was from wayy back before when i first got my imagio..been through so many changes so i don't remember much anymore. lol.
