Official site for the series of Spectrum art books (of which I have several). They always contain a wide range of talented artwork- I highly recommend them.
Photomanipulation isn't my favourite form of fantasy art but I thought that this website was so nicely laid out and helpful that other people might find it useful.
Nice website featuring several high quality galleries. Artists include Alan Lee, Dorian Cleavenger, John Howe, Keith Parkinson, Todd Lockwood and more.
My favourite art site, featuring a wide range of artists, subjects, mediums and styles! You can upload your own work as well. Better than Elfwood and Epilogue IMO!
