We have started working on this, but this is complex as by default SPO lists do not have a concept of images stored in them. This is the top item on our SharePoint connector team and we are actively working on it.
Sadly, don't have a timeline due to the complexity of the problem.
We announced at Ignite that we will enable support for adding attachments to list items by the end of year. That will be the first mechanism to capture and store images in SharePoint list we will be able to provide.
Nearing the end of January 2018... any update on this item? I really need an easy way of saving an image from my powerapp to my sharepoint custom list!
We were targeting uploading as attachment to list item for end of December but ran into issues which have delayed the release. We actually had to backtrack from our design and re-implement a newer design. We are still working on implementation of new design and hopefully will have this by March. Sorry about the delay here, we know how much everyone is depending on ability to attach files.
