I want to use this picture to engrave on my Black Macbook: http://upload.wikimedia.org/wikipedia/commons/0/0a/The_Great_Wave_off_Kanagawa.jpg I go to the EtchAMac website and browse to the picture. It then says uploading but when it gets to 100% nothing happens. Shouldn't I be able to resize it and the like? Am I doing something wrong? Here is a screenshot of it: http://img239.imageshack.us/my.php?image=picture1fy0.png How much would it cost to do this? Can I put two engravings on my Macbook?
