Cover images are strongly unrecommended on this board! It can cause DVD player problems and could damage the disc bearing it unreadable. Your better off with a Sharpie or just a jewel case slip.
I am sorry but this is incorrect. This can be done using either inkjet printable discs, you have to have a printer with the capabilities or else you have a lightscrible capable printer and discs. Having an image of this type has NO effect on the quality of the disc.
@sean2525 As usual, listen to Gwendolin she is 100% correct. I think gogochar was referring to stick-on adhesive labels which are bad and will harm to the disc. I'd stick with inkjet printables over lightscribe. I have lightscribe and have been unsatisfied with the monochrome technology. Edit you are double posting and this will cause confusion between threads. One of these needs to be closed. http://forums.afterdawn.com/thread_view.cfm/362069
First you have to have a lightscribe capable drive to burn the image with the software which came with the burner which installs in Nero. It may be there in the newest version of nero 7. You have to have lightscrible capable dvds also. Then you can burn an image onto the disc with nero. Otherwise use injet disc and epson or Canon(non usa)capable printers. OR a sharpie.
