Hello there, I've registered a new domain - Pixool.com

My sister actually made it up, I was trying to think of a name for an image uploading site and she suggested "Pixool" and said it sounds like Pix Cool and Pixel The slogan could be "Cool pics need cool hosts" if that doesn't sound too good, I'll just use the casual image hosting slogan "Store your images online FREE!"

What are your thoughts on this name? Is it brandable in your opinion?
