Updating Specific Product Files
While the recommended apparel PNG file will be automatically resized for all products, it might not be optimized for all of them. For more specifics, you can find a full list of the best file sizes for each product here and templates for all products here. We've also created a product guide on how design sizing works for non-apparel items here.
Once you've created a new file for a specific product, you can replace the old file from the Manage Products page, using the Customize Design Files by Style button.
This will open a pop-up window with a drop-down menu that has all your existing products, as well as their recommended file sizes.
Select the product you would like to update and upload your image either by dragging it into the window or selecting it directly with the uploader.
You'll see a preview of the new file and make sure to hit Update Image to save the new file. Once uploaded, you should be able to see the new file immediately on both the editing page as well as on the product page itself.
Using this method, you can have product specific art within the same design like Space Pals as shown above!
