I'd be happy to oblige - what folder do I pull them from?
Not quite that easy, so I'm glad someone with a bit of hacking experience (that's you! lol) offered
Pull /system/app/TouchWiz**Launcher.apk (the ** will be the version number. The mesmerize I have here is TouchWiz30Launcher.apk)
Open the apk with 7-zip
look for the folder named "res" inside the apk
you'll find the wallpapers there. Just drag them from the folder to a new folder.
Sammy wont jump on you, so you can upload them to a fileshare site. Then change the link in my post PLEASE lol.
Then, for fun, pull all the apks and check out the images and icons inside them. Folders named res and assets will have media inside them
