Hi Brian,
Unfortunately, the VCARD file is not supported in Office 365 but only CSV file is supported in Office 365 when bulk adding new users in admin center of Office 365, sorry for the inconvenience it caused for you.
From Google, you can import or export a CSV file or VCARD file, however, the picture sync in not supported in ether a CSV file or VCARD file for the time being.
Please view this post from Google Product forum http://productforums.google.com/forum/#!topic/gmail/4k6txNcLmao.
I suggest you post your concern in Microsoft Developer Network, there would be better resources to address your concern.
Thanks,
Sean Xiao
