File upload filter

[Manish Hatwalne]

Can I apply filter to following type of input control? I only want user to upload jpg files. How can I ensure that?

<input type="file" name="theFile">

TIA,

function CheckIt(){
  theFile = document.formName.fileName.value;
  theType = theFile.split(".");
  theExt = theType[theType.length-1];
  alert(theExt)
}

That is the basic idea....BUT you should always check it on the server TOO.
