php upload form (vista vs xp)

[UrbanTwitch]

OK so recently, I create an image upload script for fun. Here is part of the code

 

if ((($_FILES["file"]["type"] == "image/gif") // if the file is a .gif
                    || ($_FILES["file"]["type"] == "image/jpeg") // or if the file is a .jpg/.jpeg
                    || ($_FILES["file"]["type"] == "image/png")) // of if the file is a .png

                )

As you can see it's a basic simple upload prevention but images script. HOWEVER, I tested this on vista and I got through. My extensions were all LOWERCASE such as .png, .jpg, .gif, etc.

 

However, my friend, who uses Windows XP, tried it and he could not upload ANY images. We put in the image-file-type tag inside the error and it said he uploaded things like pjpeg and x-png. What...? So.. I guess it's different for XP and Vista?

no, but it is different depending on browser.  I bet he's using IE vs. you using FF or visa versa or something

He uses IE. That's why, I guess.
