It’s kinda “issue” , main cause of problem that Apple native automator does not sees that element , that is why Appium also does not sees it.
As I recently discussed with iOS developer , this problem occurs only when developer wraps image inside other custom view ( example in TableCell ).
As i written in other post , u can take nearest element , after take coordinates of that element by element.getLocation() . Then shift coordinates point towards your Image , it will give you opportunity create relative tap by coordinates.
