The following proposal is nothing for production use.
It is just a hack around the limitations of mp3tag, ...
... because currently there is no shared memory between two tracks.
Unfortunately there is no action to remove a (temporary) file from the filesystem.
Begin Action Group Format TRACK#Set TRACK count from given number
For some reason Mp3tag executes the export as recently as at the end of action group, so the action group has to be performed twice.
The export output file must not exist when starting the procedure.
You may split this process into two independent action groups
You can use the export feature of Mp3tag to create textual output, and name the filetype of the output file as you wish, you know that already, I am sure, there are many examples in the forum.
Yes, the problem is, that Mp3tag does not 'invoke' or 'execute' or 'launch' an export script from within a running action.
When using [Strg+E] Export, the just created export script will be 'launched' and so it can be 'executed'.
If the Mp3tag export feature creates a text file named like "however export script.cmd", then it will be automatically launched to the system, perhaps a Mp3tag warning will come up (maybe adjustable in Tools/Options), then the cmd script will be executed.
For several hours each day I sit behind a firewall that does allow access to that picture server you prefer to use.
So could you either please upload the pictures to the mp3tag server or describe what they show?
