You did not mention which model you have. This is important due to jacket pictures requiring alot of memory which you may not have.
Might I suggest you read a few posts down about SuperNudelist and try out SuperNudelist from the Pronto Files section unless, that is, you have your heart set on Jacket Pictures. Please be aware that SNL also requires CCFTools. Both programs are available in the Pronto Files Section?
Since you are new to this, I might also suggest that you hit the website in the last post on the SuperNudelist thread: [Link: BruceHartley.com]
and Leo Davidson's original SuperNudelist website (from the SNL release notes) http://www.pretentiousname.com
