Hmmz, it seems that I need to add 30 characters here, even though an image says more than a thousand words... When you think you have solved it, please read this hint:
What kind of cookies do I like?
The colors are slight off, filling it in it makes:
I Like Cookies
then filling it in with my old ass paint program I get:
which is decoded in morse to
I like cookies
Filling in the image- there's an off-white section that provides the message
The message in the image says "I like cookies" Although the image appears completely blank opening it with an image editor and using the fuzzy select tool reveals the words.
