For the Image widget type, expand ability of where to select the data source from to include option that matches that of the Metric widget - where you can choose a cell from a sheet.
When using a workflow via Control Center, we intake Clients and capture their logos in a cell (as there is a nice option to insert image to a cell). Then we have a Dashboard that is automatically provisioned and pulls this logo. To allow this to be automated, we currently must use a Metric widget on the dashboard template to capture the data value from the sheet. However the metric widget does not have similar functionality as the Image widget that allows for dynamic sizing control (fit / fill image) in the widget shape. This leads to the logos being cut off and the user forced to scroll to see the image properly (notice cut off image and scroll bar in attached screenshot).
It seems like this could leverage (what appears to be) existing functionality to select the data source as a cell value for an image widget type (instead of just upload, google drive, box, dropbox, onedrive) - and then we would gain the benefits of the image widget type functions in the control center-managed auto-provisioned solutions we build.
