<script>
function checkit(){
var str=document.forms.form1.fill.value
var len=str.length
var pos=str.lastIndexOf('.')+1
var rest=len-pos
var ext=str.substr(pos,rest)
if (ext!='gif' && ext!='jpg')
alert('u shuld select some picture')
}
</script>
</head>
<body bgcolor="#FFFFFF">
<form name=form1 >
<input type=button value="c file accepts" onclick="checkit()">
<input type=file name=fill >
</form>

Here is a link to a way to do this in JAVA:
Hi,
by using the input type=file tag, is impossible to do this.
(the accept=".." parameter not work).
you may use the common dialog in javascript:
function browse_file() {
var cdl = new ActiveXObject"MsComDlg.CommonDialog"
;
cdl.maxFileSize=256;
cdl.filter="Imagens|*.gif;*.jpg;*.bmp";
cdl.showopen();
alert('Selected file: '+cdl.filename);
}
this work fine.
