There is currently no obvious way to bring images from the new 'image' column type into a PowerApp or write from PowerApps to this column.
This new column in SP is a great feature but all my clients that have started using it are now REALLY frustrated that they can't use the images in PowerApps.
SharePoint lists and PowerApps are such a great combination, please can we have integration for this new feature?
Yes, absolutely essential for both PowerApps and Power Automate. I'm currently resorting to converting an uploaded image (using the add image control in a form), converting it to a base64 string, then Patch()ing the string in a secondary Sharepoint list correlated to my main Sharepoint list via a LookUp() function.
It 'works', like a hole-ridden rubber dingy patched together with duck tape technically 'works', but I'm not gonna use to to sail the seven seas.
Power apps will soon support the image column type from SharePoint Online/Microsoft Lists.
