Note: New Accounts: For best quality photos: After you click "Upload" (bottom right corner), there is an "Upload Preferences" option. Here you can change the resolution from the default "Standard Resolution" to "Full Resolution" and also remove the red eye correction. If you have already done this before, your preferences should be saved.
