the profiles are not touched on update and the default images will get overwritted but only in the folder, wont update the device, but GOverlay makes a backup of them on every update from which you can restore them.
If you want to be 100% safe,
1) Export user-specific data:
a) export all your profiles from within GOverlay so you can save them in files
b) Check the FAQ to do it using the registry, from which you save EVERYTHING goverlay stores for the user, so its a 100% secure way to restore profiles and options for goverlay itself.
2) Make a full copy of the GOverlay folder. This way you can have the older version and your images backed up.
If something goes wrong after the update just restore the saved registry file and run goverlay from the old folder.
But i've not received any reports of issues with the updating procedure so it should be pretty safe to do w/o any of this steps, anyhow, if you are concerned and modified images just make the backup first.
