Picture Visibility Issue

The link you have provided is your IMDb user profile page and not your IMDb name page.  To understand the difference between the two page types, please see https://help.imdb.com/article/imdb/general-information/what-s-the-difference-between-an-imdb-page-and-user-profile/GHQEDYZ5DJ5Y8G5S

In order to add a headshot to your IMDb name page, an active paid IMDbPro subscription is required, please see https://help.imdb.com/article/imdbpro/manage-your-imdb-page/manage-your-images/GYJLH267T2DMYJ53 for details. 

Hope this helps.
