Are there any free images?
Just because you found it on Google Images - does NOT mean you are free to use it. Images on Google image searches are covered by international copyright law and thus it is not a "free for all." Some designers, photographers, artists and typographers offer “free” licences to use their material but it is important to be aware however that these works are still subject to conditions including attribution (crediting the artist) or for personal/student use only. Please read the terms and conditions before using anything from the web.
You are liable if you supply Killer Aesthetic with any files with copyright restrictions.
