In reference to this post https://powerusers.microsoft.com/t5/General-Discussion/Save-Signature-to-SharePoint-List/m-p/77038#M...
Is it possible to take the button that collects the signature and have it save the form at the same time? Then I would not need the button and remove one of the steps.
Go to Solution.
You could collect the signature as images collection, but you cannot submit and save it with SharePoint list editform. It is not yet supported in PowerApps to upload any images to SharePoint list.
The blog I suggested is how you upload images from powerapps to SharePoint library, not list.
