The following code causes a fatal error in System.Drawing.DLL whenever I compile in Release, but not in Debug:
I know little of C# and it''s ways. However, that hasn''t stopped me from answering anything before, so... :\
It wouldn''t be something like the paths are relative, so they might end up pointing somewhere else in Release rather than Debug. e.g. "./Debug/images/attack0.gif" becomes "./Release/images/attack0.gif" during Release?

Yeah, but the images folder is present and accounted for in both the release and debug directories.
Is it a fatal error? Or is an exception thrown?
Wrap the code in a try/catch block OR handel this event:
AppDomain.CurrentDomain.UnhandledException

That just breaks it more 
Basically, if the is thrown then the pictures aren't loaded and there are lots and lots of null reference exceptions

Is there a need for clarification?

Hrm... I guess the problem is actually as follows:
If I use the code above to load the images I get a System.OutofMemoryException at gunImage = Image.FromFile("images/gun.gif");
if I replace that with ''gunImage = new Bitmap("images/gun.gif");'' I get a System.ArgumentException (Invalid Parameter Used) in the same place instead of the out of memory exception.

Again, I''d like to cover myself by declaring that I''ve never touched C#...
"If the file does not have a valid image format or if GDI+ does not support the pixel format of the file, this method throws an OutOfMemoryException exception." - MSDN
Strange, but true. Who''d have thought an OutOfMemoryException could indicate that?!

from the .NET framework documentation about the Image.FromFile() method:
Yes docs are your friend. I''d find out which file formats and pixel formats GDI+ supports and check your file if it matches them.
