Like Mariana, the title of an image attracts me more than a thumbnail. I almost always pick a movie by how much I like the title of it. If I don't like the title, there is slim chance that I'll like the movie. I find this to be true nearly 100% of the time, no matter how attractive they make the lead-in clips look. I use the same criteria for browsing art galleries on the net.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
