Easy to use - just open the image marked folder "Image" and right click the image holder, choose "edit contents" and paste your image over the included one. then delete my old shirt design and save, it will update the main file. If you're asked for "displacement map" just browse to the file "texture.psd" which is also included. Brick wall is optional, you can disable it and use either white or black background (or you can import your own backdrop image)
