imgboard . php

So I was browsing /b/ when it crashed, and a download popped up for imgboard.php

Haven't gotten a chance to look through it yet. Is this win?


switch ($size[2]) {
      case 1 : $ext=".gif";break;
      case 2 : $ext=".jpg";break;
      case 3 : $ext=".png";break;
      case 4 : $ext=".swf";error(S_UPFAIL,$dest);break;
      case 5 : $ext=".psd";error(S_UPFAIL,$dest);break;
      case 6 : $ext=".bmp";error(S_UPFAIL,$dest);break;
      case 7 : $ext=".tiff";error(S_UPFAIL,$dest);break;
      case 8 : $ext=".tiff";error(S_UPFAIL,$dest);break;
      case 9 : $ext=".jpc";error(S_UPFAIL,$dest);break;
      case 10 : $ext=".jp2";error(S_UPFAIL,$dest);break;
      case 11 : $ext=".jpx";error(S_UPFAIL,$dest);break;
      case 13 : $ext=".swf";error(S_UPFAIL,$dest);break;
      default : $ext=".xxx";error(S_UPFAIL,$dest);break;
    }
so they specifically disallow perfectly useful image types‽
