asked on
Misc. code in an image?
Is it possible for someone to insert misc. or possibly dangerous code into an image file such as a .gif, .jpg, .bmp and so on?
The coding i am referring to is something like html tags, javascript and any other possible code format.
And if it is possible, how?
Thanks in advance.

> .. or how i would tell a coded image from a safe one?
you can't if you don't know what you're looking for.
Any image may be infected, use lynx or links or w3m if you want to be safe :-))

Yes. However, this code would not be executable unless the code was extracted from the image by some other program. Therefore, for the code to be exectuted, the target machine would have to be infected already, unless there are other weaknesses inherent to the Microsoft OS of which I am unaware, when the image was cached by your browser.
Moral: Keep your virus scanner updated.
