Memorability and stickiness are the most important features of an image. I never want to stop looking at it, and even when I finally do stop, I like to recall it in my mind's eye.
I only remember the image that evokes wonder and mystery. To do so, the image must possess an amazing concept combined with astonishing technical prowess/dreamy coloring/a wow-inducing background/ties to my experience (several of the above, actually)... and, most importantly, some Ingredient X that I can't put my finger on. That Ingredient X is what makes or breaks the picture, even if the artist is less skilled.
The rest of the options are too easy and too common, and thus all too forgettable...
To me it's less about which emotion it is and more about how evocative the piece is. What I care about in a work of art is whether or not it really makes me feel the emotion it's trying to convey, not any specific emotion in particular. Wonder, cuteness, action, romance, even more depressing emotions...all mean a lot to me if the work of art makes me feel it each time I look at it. I think this is also why the novels I gravitate back to for re-reading are the ones that hit me harder emotionally or give me a gripping adventure to follow (or are just plain fun). If it doesn't engender those emotions in me properly, I'm not going to care enough to come back to it, no matter how beautiful or well-crafted it is.
I picked action and adventure but really it's impossible for me to choose. a lot depends on my overall mood at the time plus many, many other factors. it's possible for a piece with any of the emotions you listed to strike a deep chord in me.
