I posted earlier about modal windows/popups but i remember awhile back that websites such as yahoo or imdb.org had images kind of floating around to get attention but the images weren't just square or rectangle.. but shape of image .. so if it's a like a human figure image.. that will show only while the background of site will show through any unfilled parts of image... is this possible? i plan on drawing something in illustrator/photoshop and would definately get there attention to retain the shape .
