facebook – How to automate bulk upload on Hootsuite with images?

I want to publish bulk publications with the csv download utility on Hoot Suite. However, there is no clear way to automate the download of images for Instagram and Facebook. All the examples I've found require the user to manually click and edit each message by selecting the photo from my local computer.

Is there a way to format the fields in the csv download program to extract them directly from an url? For example, if I post on imgur, can I use these image URL paths in one of the fields?
