[pob1-port] [Linux] - Fix broken header images. (#1603)

* Apply changes from PathOfBuildingCommunity/PathOfBuilding#9092

* Fix merge conflict

Now uses lower where the asssets are used so we don't need to change the names and have a block for the spell checker to skip

* Only lower case load calls
