Image preview in upload image section in my site is not working in IE8+ browsers. But Working fine in IE7 and IE6. I am using this below code for image preview functionality. JS:
var loadImageFile = (function () {
if (window.FileReader) {
var oPreviewImg = null, oFReader = new window.FileReader(),
rFilter = /^(?:image\/bmp|image\/cis\-cod|image\/gif|image\/ief|image\/jpeg|image\/jpeg|image\/jpeg|image\/pipeg|image\/png|image\/svg\+xml|image\/tiff|image\/x\-cmu\-raster|image\/x\-cmx|image\/x\-icon|image\/x\-portable\-anymap|image\/x\-portable\-bitmap|image\/x\-portable\-graymap|image\/x\-portable\-pixmap|image\/x\-rgb|image\/x\-xbitmap|image\/x\-xpixmap|image\/x\-xwindowdump)$/i;
oFReader.onload = function (oFREvent) {
if (!oPreviewImg) {
var newPreview = document.getElementById("imagePreview");
oPreviewImg = new Image();
oPreviewImg.style.width = (newPreview.offsetWidth).toString() + "px";
oPreviewImg.style.height = (newPreview.offsetHeight).toString() + "px";
newPreview.appendChild(oPreviewImg);
}
oPreviewImg.src = oFREvent.target.result;
};
return function () {
var aFiles = document.getElementById("imageInput").files;
if (aFiles.length === 0) { return; }
if (!rFilter.test(aFiles[0].type)) { alert("You must select a valid image file!"); return; }
oFReader.readAsDataURL(aFiles[0]);
}
}
if (navigator.appName === "Microsoft Internet Explorer") {
return function () {
document.getElementById("imagePreview").filters.item("DXImageTransform.Microsoft.AlphaImageLoader").src = document.getElementById("imageInput").value;
}
}
})();
CSS Style:
#imagePreview {
width: 160px;
height: 120px;
float: right;
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(sizingMethod=scale);
}
</style>
HTML:
<html>
<body>
<div id="imagePreview"></div>
<form name="uploadForm">
<p><input id="imageInput" type="file" name="myPhoto" onchange="loadImageFile();"><br>
<input type="submit" value="Send"></p>
</form>
</body>
</html>
This code runs in IE 6 and IE7 but not runs in IE8+. Anyone knows what is the issue in above code. Running example link: https://developer.mozilla.org/files/3699/crossbrowser_image_preview.html

Please check this post:
How to upload preview image before upload through JavaScript
I have tested, one thing must to do:
IE8 needs a security settings change: internet settings, security, custom level : [] Include local directory path when uploading files to a server ( ) Disable (o) Enable
After enable this option, your demo works fine in ie8! https://developer.mozilla.org/files/3699/crossbrowser_image_preview.html
