is there a certain website just for downloading skyboxes?
Some places I found googling:
I'm sure there's lots more. I'm looking for some high quality ones as well.
Go to http://www.hazelwhorley.com/skyboxtex2_bitmaps.html these are the same skyboxes for free
Lots of free vegetation-rich 3D SkyBoxes at FarmPeeps.com in the 3D-DevLog section. Free downloads such as the forest clearing sky boxes have aplha and depth maps so you can add fog or darkness effects without obscuring fine detail. http://www.farmpeeps.com/farmpeeps_products.html
How do I put a rendered texture on an object?
