BEST PRACTICES FOR UPLOADING IMAGES
You may notice that you get a warning that your image is too low of a resolution to upload. This ensures that images meet the minimum requirements to print a clear image without appearing pixelated or fuzzy. If you receive this warning it is recommended to print the image at a smaller size or trying to upload a better quality image.
Make sure you have the proper orientation selected before trying to upload an image.
Images saved from Facebook to your phone will most likely be too low quality to print.
It is important to note that saving images to your phone will often reduce their quality. For example downloading images from a professional photographers online gallery. When possible it is best to download and save to a computer to ensure you are uploading the best quality image.
