Do you use images in your blog posts or are they all text?
Option D and A in that order please.well I guess you can :
A) Fotoshop the images
B) Buy a licence to use the image
C) buy an exclusive ownership to the image (so nobody else can buy it / use it)
D) go to hell [Borrow/rip off the images]
E) contact owner and seek permission (and give em credit/link lurve i guess)
