Now interesting thing with this challenge is you do not need to search for clues on the page for images or anything else, but link to the image is offered to you. So let’s try and open it.
Now if you open this image there is high probability that you will not see a thing, more interesting is that Firefox is able to show you this image. But since I tried this challenge in Google Chrome at first I noticed that image is not valid. And even if you save image on your system and try to open it you will see message something like invalid image or similar.
Of course I am talking about following image:
Now since this image is not valid this can only mean that it is not formatted correctly and that there is some data hidden inside. So what you should do now is to open image in the notepad or some other simple text editor.

Level 16: unavailableÿÀ ÿÄ K ÿÚ ? ¿€ ?ÿÙ
This is the code you will see when opening image contents in the notepad. Notice the following line: Level 16: unavailable now this gives us important clue how to proceed. We will just enter unavailable as folder and see what we get. So the URL for level 16 is following:
