// This code is useful for popup pictures (e.g. thumbnails  //
// you want to show larger, such as a larger version of a   //
// product photo for example) but you don't know the image  //
// dimensions before popping up. This script displays the   //
// image with no window border, and resizes the window to   //
// the size it needs to be (usually better to spawn it      //
// large (600x400 for example) and let it auto-resize it    //
// smaller), and if the image is larger than 90% of the     //
// current screen area the window respawns itself with      //
// scrollbars.                                              //
//                                                          //
// Usage:                                                   //
// window.open('showpic.php?src=big.jpg&title=Big+picture', //
//   'popupwindowname',                                     //
//   'width=600,height=400,menubar=no,toolbar=no')          //
//                                                          //
