Upon successfull reading an image file, this computes a SHA1 hash of the image and saves it with the picture tag in the log file. When a file is not successfully loaded (for example because the log was created on a different computer) we look up the hash in a dictionary that maps hashes to local file names. That dictionary (actually two for both directions), is loaded on startup and saved upon destruction of the main window. Signed-off-by: Robert C.
