Right, have forced myself to look again. Am now not scared. A quick Google found \link{http://www.castleofspirits.com/hauntedpainting.html\this}, which, for those who don't want to see the damned thing ever again, basically says:
"Bill (Stoneham, the artist) tells of how he painted Hands Resist Him in 1972, the boy in the picture being himself, the hands being other lives, the windows/door being a thin veil between waking and dreaming with the small doll like girl being the guide through.
Bill does not know how his painting ended up abandoned as described by the Ebay.com seller, but he does know a gallery owner where the painting was originally displayed and sold at, and a Los Angeles Times critic, who reviewed the show, were both dead within one year of the painting being shown."
A dead gallery owner and an expired critic do not a haunted painting make.
Phew, I can sleep tonight!
