Already tried it, no luck...
Well, here's how you can do it yourself:
1) Download the image. Use an image editor to scale or crop it to your monitor's resolution.
2) Get a resource editor. I use XN Resource Editor. Google it for a link.
3)
Make a backup of op2shres.dll before you do anything else!4) Open op2shres.dll with your resource editor. (Note: I'm assuming you're using XN Resource Editor)
5) Open the Bitmap folder.
6) Look for and open the 190 folder.
7) Right click the image file in the 190 folder and click "Delete Resource"
Right click the Bitmap folder.
9) Find the newly created folder. Open it.
10) Right click the item in this folder and click Properties.
11) Set Name to 190 and Language to English (United States).
12) Save it. Run Outpost 2.
