For inserting image tag, all I read is using expressions like %album% and %artist%, but not just the filename without extension (apparently \_FILENAME is the whole thing, e.g. joe - songA.mp3).

Q1) What do I use to declare the filename without extension?

Q2) Regarding those other expressions, like %album%

```
  Are they case-independent?
  How is a field like Album Artist handled? Is it %album artist% or %'album artist'% (single quote to delineate a string with blanks) or something else?
```

1. Use %\_filename%.

2. No, variable names are not case sensitive. Mp3tag is a little inconsistent in its internal usage and in the documentation, but you shouldn't have to worry about it.

3. Album Artist is ALBUMARTIST in Mp3tag. See the [field name mappings](https://docs.mp3tag.de/mapping) help page from the documentation. There are no internally recognized field names that contain spaces. I suppose you can create them as user defined fields, but I've never done so and couldn't say how you need to represent them in Mp3tag.

Thank you! That worked. I did not know about the tags page and first jumped into a forum discussion with my issue where the links provided took me to pages that had no description or link to the page you advised, along with others that I now have found. So I mistakenly thought there was no such documentation.
