fixed input to extractImageBlockType to be sent to the server properly (#122)

### Notes This PR fixes the input for `extractImageBlockType` to be sent as an array instead of a comma-delimited string so that the input settings are respected server side. ### Testing Manually inspected server-side after change that the correct input is sent properly. Updated integration test.
