Dear Jon/Agnes,
The ZVI_reader is presumably being called from the HandleExtraFileTypes
plugin which is distributed with ImageJ in the plugins/Input-Output folder.
Here's the relevant code snippet :
// ZVI file handler
// Little-endian ZVI files start with d0 cf 11 e0.
if (name.endsWith(".zvi") || (buf[0]==-48&&
buf[1]==-49&&buf[2]==17&&buf[3]==-32)) {
IJ.runPlugIn("ZVI_Reader", path);
width = IMAGE_OPENED;
return null;
}
Basically if ImageJ can't recognise a file it calls HandleExtraFileTypes to
see if that contains a code snippet that will handle opening that file type.
Your directory most likely contains a file that is being recognised by the
code snippet to handle ZVI files - ie a file that ends in ZVI or starts with
the 4 bytes d0 cf 11 e0. Presumably the Thumbs.db file does start with that
4 byte code and therefore is being opened inappropriately.
I think someone has already noticed this problem and the latest version of
the HandleExtraFileTypes plugin fixes it:

Greg.
