Ignition not showing images

Hello, I am experiencing a slight problem with one user. A lot of the buttons that are used have images next to them to increase the visual aspect of it. The user is logged into three computers, and one of them is not showing the pictures but still connected to the server and getting live data. The other two log ins which are all on separate computers are displaying the pictures and everything. Any ideas on what could be causing this problem?

What versions of Java and Ignition are you using?
