i'm trying to make birthday invitations on the computer for my son. I only have regular "Paint" program on my laptop and I am trying to photoshop his photo into a Yo Gabba Gabba background but I cant seem to figure out how to make it transparent when I copy and paste his picture into the background even though i erased perfectly around his body frame to make it look better. Can anyone help or does anyone have any programs I can download free and that won't give me VIRUSES!!!
