md5 for cover

I have a problem with exportation in .xml : I want to put md5 of the album's cover but I don't find the specific term. Maybe %_cover_md5% ?

As you cannot see the md5 value for tags separately you would have to export the covers first, then set the Tools>Options>Tags>File extensions so that MP3tag also reads the jpg-files.
Then read the folder so that the jpg-files show up in the files list.
Then create a report that includes the variable %_md5% (for the whole file). This will create the md5-value also for jpgs.

Esp. if you want to see covers in XML you would have to have the files in the file system anyway.

the code for my .XML :
