I am wondering if anyone knows if it is possible, and how to, have an image upload field that uploads the images to an external cloud storage like Google Drive, Drop Box, etc?
Right now, all I can manage via Zapier is the url that links back to the image stored on Knack's servers.
Currently, Knack does not have a feature to upload images to an external cloud storage. We will likely consider adding this feature in the future, however, there is no timeline for this at the moment.
If you would like, you can share your request in our feature request forum, here: https://support.knack.com/hc/en-us/community/topics/200940707-Feature-Requests.
If you have any further questions, please don't hesitate to ask.
This can be done using Zapier. An update to the record in knack triggers a “zap” that looks for new docs/images, and uploads the new item to a unique folder on google drive, then writes the folder urL to the Knack record. Zapier support helped me create the zap - awesome help from them.
