Email/Send Files
We can accept files up to 20M via email. If sending more then a handful of images it is typically best to store the files in one folder and zip them for sending.
Set Up a Google Drive Folder
Or if you have 25 or more images, we suggest setting up a folder on Google Drive and sharing that file with us. See Instructions below on setting up a Google Drive account and folder, no charge services.
Go to drive.google.com
On your computer, go to drive.google.com.
Tip: You can choose between Home and My Drive as your Google Drive start page. To change your start page, go to Settings 
Settings. Then select your preference

Share & organize files
