Show/Hide images on a asharepoint page based on a value pulled from database

Hi All

I am working on a sharepoint 2013 application (migrated from Sharepoint 2010). There are few sharepoint pages(.aspx) using server side code in the page (inline code).

The code does the below:

Gets the current login. 

Connects to database

pulls value of the logged in user and based on the value images/webparts are made visible/invisible.

But i dont want to use inline code. Please suggest how i can achieve the above functionality without using inline code.

Thanks in advance
