Aviva,

maybe it's time to start learning a bit about IJ-macro coding.
You may have a look at the manual "Built-in Macro Functions"

<http://rsb.info.nih.gov/ij/developer/macro/functions.html>

You may especially be interested in the call:

getMetadata("Info");

With Wayne's great "Process>Batch>Macro" command you may now modify
the above Wayne's macro code to read:

path=File.directory+File.name;
date=File.dateLastModified(path);
size=File.length(path);
mdat=getMetadata("Info");
print(i+", "+getTitle+", "+date+", "+size+", "+ mdat);

which should do the trick. (At least it does so for me.)
