The paintings are available , if one is over 18 years of age and registered , at ISA. Go to Warlokk's Dungeon, look for a post called " Skintone changer by Christianlov-Bodyshape compatible", go to page 6, there is a link ( actually two) to download the 4 painting set. I searched at his blog, which has lots of awesome stuff, much of which I'd not seen previously, but no luck with the paintings. Blog is here...

The paintings do allow you to change to those skintones only if you have them as separate items. You don't need to get them all, just pick and choose the ones you may wish to use.
