please use any graphic software (like gimp, photoshop, corel) - fill whole template with image & keep all the important elements inside violet area. dotted lines are approx. cutting lines & there is about 3mm of safe margin (inside & outside dotted line = the gray area) - it means image can shift in the process by max of 3mm in&out of each side. please avoid any "line"-like borders, it will look odd when there some misalignment happens. please make 2 images, one for fron and one for back. i made it a bit transparent to show fitting to template below

please make print-ready graphic ("what you see is what you get!") like the left image shown above. best results would be RGB with 300-600dpi resolution, good quality JPG or TIFF/BMP (our template JPG file has those parameters set already). if you still dont how how to make it, send your unedited image and we will try to help make it printable - but this one is easy, just a square image and to remember that small margin will be cut during whole process
