The .gif or .jpeg means nothing. They are both just visual ques. That's why jpeg jpg JPEG are all the same. The browser uses the mime type to determine what file it is to render so changing the extentions wont make a difference. You can save the file to your desktop and rename it from
egy1w2.jpg to
test (yes no extention) then create a file named
proof.html and add the following code:
Code:
<html><body><img src="test" /></body></html>
You'll notice that it still works just as well.
You can play around and make something like make a file
arhive.jpeg that when you try to open shows as a image but is really an archive of some files so you can right-click and extract them like any archive.
