Editing music advertisement

I just found out today that I couldn't use any original images from google if they were not edited and I realised that my final magazine advertisement had an un-edited image from google of the WW1 propaganda - you can do it poster. Therefore I changed it and edited the image on Picasa as photo editing software. I used a focal lack and white as this would be eye catching to the audience as it brings out the colour in the woman's facial expression on the poster. Now I have edited the image of the poster my final draft of my advertisement is now finished.
