You can keep resized photos in your albums for viewing purposes and upload originals only when needed. In such a case, if the pixel size of a photo ordered is not sufficient to provide a decent level of quality, you will be asked to upload a full-size file. To automate the process, it's reasonable to upload original images.

Minimum resolution for printing your photos with sufficient quality is set through the "Selling" section of "My Account":

1. Make sure you are logged in and go to the "My Account" page.
2. In its "Settings" section, click "[ Change ]" opposite the "Selling" subheading.
3. In the "Printing Resolution" dropdown menu, set the minimum resolution and save changes.
4. On the confirmation screen, click on the "Back to My Account" link to continue.
