}
What the fileCheck function does
Uses img as a parameter, see if picture file has both a height and width greater than zero. If so, call the next function, otherwise, try again for a while longer - maybe something is still loading.
function fileCheck(img)
{
if( (picfile.width!=0) && (picfile.height!=0) )
{
makeWindow(img);
}
else
{
funzione="fileCheck('"+img+"')";
intervallo=setTimeout(funzione,50);
}
}
function makeWindow(img)
{
ht = picfile.height;
wd = picfile.width;
var args= "height=" + ht + ",innerHeight=" + ht;
args += ",width=" + wd + ",innerWidth=" + wd;
if (window.screen)
{
var avht = screen.availHeight;
var avwd = screen.availWidth;
var xcen = (avwd - wd) / 2;
var ycen = (avht - ht) / 2;
args += ",left=" + xcen + ",screenX=" + xcen;
args += ",top=" + ycen + ",screenY=" + ycen + ",resizable=yes";
}
return popwin=window.open("","_blank",args)
popwin.document.open()
popwin.document.write(''+img+' ')
popwin.document.close()
