apparently he copied and pasted the image of the other site onto mine,this couldnt be how sites get recoded is it?
If you need graphics for the site then s/he needs a suitable program, photoshop, can be illustrator, corel draw etc.. Copying another sites images, no thats not how its done especially for paid work. Then again it depends on the terms the both of you had. Hope its just a misunderstanding and you can can get your money back.
