While playing around with thumbnails (thanks to Charles Philip Chan 
for the link!) I came up with the following code:

  file = @"~/GNUstep/Images/TextSystem1.png";
  absolute = [file stringByStandardizingPath];
  NSLog(@"file: %@, absolute: %@", file, absolute);
  absolute = [[NSURL fileURLWithPath: absolute] relativeString];
  digest = [[[[absolute dataUsingEncoding: NSASCIIStringEncoding]
                 md5Digest] hexadecimalRepresentation] lowercaseString];
  NSLog(@"file: %@, absolute: %@, digest %@", file, absolute, digest);
  file = [[[@"~" stringByAppendingPathComponent: @".thumbnails"]
              stringByAppendingPathComponent: @"normal"]
             stringByAppendingPathComponent:
                 [digest stringByAppendingPathExtension: @"png"]];
  image = [[NSImage alloc] initByReferencingFile: file];

But this does not give the correct result. According to the 
specification the URL file name "absolute" should be something like
file:///home/fred/GNUstep/Images/TextSystem1.png

but in GNUStep I do get:
file:/home/fred/GNUstep/Images/TextSystem1.png

I think GNUstep is wrong, according to RFC 1808.
