Click on the "get started" button on the right hand-side of the website's homepage. Click on the "upload a photo from your computer" button, and browse the image files to select the photograph you wish to turn into a blingee stamp. You should now see the full-size selected image on your screen.
Click on the "geek" tab, which is located above the image, then click on the "smart scissor" option.
