If you are uploading a large image (over 8 MB) or multiple images, you will find the process much faster if you use an app such as DropBox.
This file storage and file transfer app is free and designed to handle large files. In fact you can send us any number of files as long as all the image files combined don't exceed 2 gigs of data...and that is a lot of image data!
When uploading files to us you'll have an opportunity to include notes or instructions and if sharing more then one image, be sure to let us know the final print size for each image file you are sending. That way we can quickly match them to your original order.
You can download your DropBox App at www.dropbox.com
