Under 2d texture, you next have to select "image map" before you can browse to the texture. Vicki 1 and 2 have a lot of different material groups (sodoes 3, but they are different), and without a MAT file you will have to apply the proper texture to each material. Most texture sets have, at a minimum, a body texture and a head texture; there may also be maps for bump and transparency. You need to look at your particular set of textures and determine which texture is which. The head texture you should assign to the SkinHead, eyebrows, eyelash, lips, nostril, tongue and teeth materials, as well as the eye materials. The skin texture gets applied to SkinBody, nipples, fingernails and toenails. I've probably forgotten some materials, but you should be able to figure out what goes where with the above info. Also, to make your life easier, you don't need to create a new node and browse for every material. For any node, be it a 2d texture or whatnot, you can right-click and copy it, and then go to the next material and paste it.
