Did you know that Google Drive is an app you can install on your mobile phone? It is and it opens up a number of possibilities for collaboration. Just go to the App Store on the iphone or Google Play on an Android phone to download the app. A green-gold-blue triangle is the app's icon.
Once you have installed it on your phone you can use it to send photos or any other type of files to collaborators (e.g. other tutors, Birthlight office personnell, etc). Here's how via screenshots from my iphone6:
1. double-click the drive icon to open it (circled in red below)
2a. Let's say you want to share a photo you've taken on your phone during a course with the BL office staff. Find the photo click the "share" button (circled in red below)
