Personally i am very much fond of dark images, that is images that convey a sense of horror, the macabre, are generally eerie and suggest hidden unlit depths of the human mind :)
Here are a few of my favourite such paintings:
First a couple by Beksinksi (these have no titles)

Then there is Goya
The witches' Sabbath

I only discovered this one lately, but i love it:
Bruce Segur- Childhood demons

And finally, an image that can be seen as both depressing but uplifting too, depending on how you interpret it:
Mihcael Whelan - Leap of faith

It would be great if you post your own favourites too :)
