Otherwise, try its alternative such as GIMP which is considered as the best after Photoshop. It is completely free and is capable of performing any kind of image editing task.

My husband and I met in October of last year and we're married that following March. I want to take all of our text messages from "Hello" to "I do" and make them into an art piece. About 18000 messages. I have the messages imported to my computer, but I need a program or website to put them on a canvas, or something. Any ideas?
