Cubemap Environment Texture: How to upload/create?

[MultiverseTraverser1]

I'm trying to change the texture of a cubemap skybox sphere I purchased, I used a cubemap generator but I don't know how to select all 6 files for the texture at once. I did a bulk upload of each square. can anyone help?

You've uploaded all six textures to SL? Then it sounds like a simple matter of the Select Face option in the edit panel. (I'm assuming skyboxes are like any other prim.)
