file upload problem in IE

[eluser]quest13[/eluser]
When I tried to upload the image in IE , the following code is not recognising JPG format in IE. But the same is working in Firefox.

Any body can help me on this ?

Code:

if ((($_FILES["uploadedfile"]["type"] == "image/gif")
            || ($_FILES["uploadedfile"]["type"] == "image/jpeg")
            || ($_FILES["uploadedfile"]["type"] == "image/png"))
{....

thanks
