I recently uploaded a poster for one of the series Maharani, It shows "Approved for Publication" but the image/poster not seen on title.

Hi deepaknaik1988- Thank you for posting the submission reference number! Further reviewing, the title link is still pending processing which is why the image is not yet on the title. This will be processed accordingly. You can keep a look at out Data Processing Times page: https://contribute.imdb.com/times?ref_=helpms_ch_ci_processing to review the processing status of both backlogged and current data. Cheers!
