• http://www.dailypainters.com/ – New paintings each day! Various artists/students submit they daily paintings here. Though most of them are small format, simple studies, you can still find some interesting color themes, compositions.
• http://www.vangoghgallery.com/catalog/Painting/ – Complete Catalog of Paintings by Vincent Van Gogh. Wow, a lot of them!  Still it’s not the same as looking at them in the museum (still remember the impression they made when I visited Van Gogh museum during last visit to Amsterdam almost a year ago), but the image resolution is quite good. Though, the color balance could be better, colors look dull.
