Hi cipher,

Do you mean that ImagePlug is trying to process Thumbs.db and the ._*
and .DS files? If so, that's odd since the default process_exp (the
regular expression for the filenames the plugin should process) of
ImagePlug would not match the any of these files. You could revert the
process_exp option to it's default, or you could prepend the current
process_exp with this a regex lookahead to filter out the problematic
files, something like:

The default precess_exp is:

Or, if I have the wrong idea, please let us know.
