I have migrated over a Table from Mssql that had an Image column I now have it in Postgres
Did SSMS see the column, and then display thousands (or millions) of images?
What you're going to need here is a GUI app (that can be a web app) which "you" have programmed to know that column is full of JPEG (or PNG or whatever) images, and so call the relevant decoding library then display at the appropriate location in a window.
