Error handling

**Steps to reproduce the behavior:**
Try to show a file that does not exist.
**Expected behavior:**
Show custom component to user, so to properly notify him/her of the error.
**Actual behavior:**
Shows only an empty image. No errors messages on the screen nor in console.

I could not find any method for error handling, particularly in case of any file load error.
Ideally one should be able to show a component notifying the user.
