First things first: You've got to be an active member of Worth1000 to create a custom portfolio. This is something that we are working on changing (i.e. so that you don't need a full account to upload custom merchandise), but for now you'll need an account.Step 1: If you don't already have an account then register one, follow the directions sent to you via a confirmation e-mail to activate your account. If you already have an account, skip to step 2.Step 2: Login to your account.Step 3: Upload your desired image. It must be at least 450 pixels wide and for the best quality printing, it should be as large as possible (but the total filesize should be less than 600k). Animations can't be printed out, so if you upload a .GIF file or .PNG file, make sure it's a static image.Step 4: Immediately after uploading the image, you will be taken to a page that displays your image. You will also have different options to purchase the image on merchandise on the left. (i.e. you should see a preview of a t-shirt with your merchandise on it). [NOTE: If instead of the preview you see a message that says "Merchandise not available for this image", it means that you have not authorized merchandise for this image and probably need to change your preferences to allow it].Step 5: Click the desired merchandise link on the left and a screen will appear that allows you to preview your merchandise. You will also be able to customize and change your choices. Click the help icons if you have any questions about what a specific area of customization means.Once you have added your merchandise to your cart, you can go back and add more merchandise (return to step 3). At any time you can edit your cart's contents by going to the shopping cart page. You can also checkout to complete your order. Both of these links will be available at the top of the website (above the navigation tabs), if you are logged in and have items in your cart.Step 6: On the 2nd page of the checkout process, there will be an area to enter discount codes. Enter the following discount to receive an immediate 15% off: W1KSELF. This will only work on images that you yourself uploaded so if there are other people's images in your cart those will not be discounted.Lastly, if you need any help during the process, please pop into Live Help and we'll be happy to assist you!
