How or where?
You pressed CTRL+F11 Combination i assume.
If how, just double-click on the image icon to open image with your default image program.
If where, locate Silent Hunter 5 install folder: C:\Ubisoft\Silent Hunter5\...
If it's Steam: C:\Program Files (x86)\Steam\SteamApps\common\Silent Hunter 5\...
P.S. If you post in the Silent Hunter 5 forum, you will get a lot more hits, ie. a lot quicker answers.
