Hi Dean,

Backslash literals in Java must be escaped with another backslash ("\\"),
because backslash is used to represent other special characters (tab is
"\t", newline is "\n", etc.).

So in your code, try:

  String imagePath =
IJ.getDirectory("C:\\Code\\Java\\MyPlugin\\images\\test1.bmp");

It would probably also work with forward slashes.
