No. I use images that I have purchased in the form of art stamps. Most of those are from Stampin' Up! and for that reason, my photos contain a watermark recognising their copyright. I adhere to all other requirements of the Stampin' Up! 'Angel Policy' including adding their © stamp to the back of each and every card I sell. The overall design of each of my cards and other products, however, is my own.
There are exceptions where I use stamps from other suppliers, such as the children's card packs.
