When I query a smaller time interval with results less than 10000 then there are images appended on the search results. However, when the results are 10000 then there is no image at all on the search results.
I am sorry, but can you add some more information with screenshots? Your description sounds like the issue that you have got but what we would like to have is steps to reproduce. If you send us some screenshots that show us the symptom, it will be helpful for our investigation.
