The puzzle was almost completed, but in the end no one posted the correct answer in the comment box. Here is the solution.
The image was a QR code, if you had right clicked and selected properties you would have found the image was called qrcode.png. This should have prompted you to have a mooch on the internet to find out what QR codes are. Wiki would have told you all about them. A further net search for a decoder should have led you to download the little applet I posted earlier. Armed with this you should have found that hidden within the image was this url

The question isn’t difficult if you have google, but a bit of lateral thinking is required with what to do with the answer. With a bit of logic and luck you should have come up with the following url.

Now this page may have seemed like a dead end, but a bit of digging and right clicking and you would find the page source code. Hidden within the code was a question, What was the date of birth of Dr. Winston O’Boogie? Again, a bit of googling and you will discover that this was John Lennon’s pseudonym. Lennon was born on the 9th of October 1940. The date format may have given you a bit of trouble, but eventually you would have ended up with the following url.

Now you have something to think about, but where do you go? Well, hidden directly under the text is more text but it’s the same colour as the background, you have to highlight it with your mouse. You will find this url.

The letters RIWDNA become Darwin.
The next one will be more difficult but will have a prize to tempt you.
