i went out to danasoft.com to check it out but the only info it had on them was that the image is created in real time. i dont know that these things are called, i thought they were called hjacks because i would see people with images in their sigs that said "free hjack" and a picture of a cow and ur ip address, but im not sure now cuz google didnt turn up much on them. here's a link to one that somebody on some messageboard was using in their sig, but i think everybod knows what im talking about, ive seen people with them here.http://www.danasoft.com/sig/penisis.jpg
