Photograph or scan the artwork or design you wish to upload onto Cafepress, and put the image file into your computer. Using a JPG image type is recommended, but you could also use a PSD, TIF or PNG file.
Open your Internet browser, and go to the website address www.cafepress.com.
Click on the link "sign in," which appears in the top right corner of Cafepress's home page. If you do not already have an account, click the "continue" button that appears in the "Not A Member Yet?" section of the page.
Click the "Get Started" button that appears under the Basic Shops section or the Premium Shops section, depending on your preference, to sign up for an account on Cafepress.com. If you already have an account, skip this step and proceed to sign-in instead.
Complete the registration process. Once you arrive at the page for your account, click on the tab labeled "Media Basket."
Click on the green button that says "Upload New Image." This will lead you to a page that will allow you to browse your computer files and upload up to five images at a time.
Click on the "Browse" button for the first file, and open the document with the artwork you wish to upload. Repeat this process if you have multiple images that you wish to upload at this time.
Check the box that states you agree to the terms and conditions of the site and click the "Upload" button. Your image/images should now be successfully uploaded on the Cafepress website.
