Although I get an email confirming my image contribution (example: IMDb update receipt #180422-161133-961102), and it has a link to view its status, I'd really like to see that contribution on the page https://contribute.imdb.com/updates/history/
Thanks, yes, it is already firmly on the list. We have changed the subject slightly and converted this to an Idea for tracking.
The background: the contribution history "talks" to the older IMDb contribution interface behind the "Edit page" button. Newer contribution interfaces, both new types (eg: images) and new locations (eg: mobile apps) go into the data processing pipeline much further upstream for speed and efficiency. The trade-off on this means such contributions do not yet appear in the old contribution history. Our aim is to consolidate everything into one contribution history view eventually, however, be aware there are plenty items ahead of this which have more of an impact for contributors. Since the new contributions are much faster and include tracking links in the email receipts, there ought to be less of a new to go to the history page for such items.
Ahead of the longer term software changes, we recently added a set of updates to the online documentation "to do" list to better explain this in the meantime.
