OFL Campaign briefing map

[grayter]

Hi guys,
I need help with my campaign briefing map (On Foreign Lands).
I know nothing about computer graphics but my map needs improvements (burnt edges and some filters to make it older and decrease the contrast). Can anyone help me with that? I would like to include it in next RC.

U mean the map in menu or the missions?
If in the menu use Something like photo shop or gimp
