I believe something like this would suffice:

You can't nest expansion operators like that. But you can just work with smaller substrings to get the result you want.

You're not closing the child's stdin. Your stdin variable is a mutable reference, and dropping that has no effect on the referenced ChildStdin.

Use child.stdin.take() instead of child.stdin.as_mut():

Specifying the full path of the command worked:

Your command would be:
exiftool -if "$Filename=~/_compressed/i" -r -TagsFromFile %d%-.11f.%e -All:All C:\photo

This command will process the files in C:\photo, check to make sure that _compressed is in the name, and copy all tags from the file with the same name minus 11 characters from the end of the file's basename.

Because you want to recurse, you cannot use a wildcard to only process the compressed files (see Exiftool Common Mistake #2 and the -r (-recurse) option).

If you want to only copy specific tags, you would replace -All:All with -TAG1 -TAG2 … -TAGn, replacing TAG# with the actual tag names.

This command will not copy some tags like ICC_Profile. You can copy color related tags by adding -ColorSpaceTags after the -TagsFromFile option.

This command creates backup files. Add -overwrite_original to suppress the creation of backup files. If this command is run under Unix/Mac, reverse any double/single quotes to avoid bash interpretation.

You need to add the file html_entities.txt to the archive. The following seems to work for me:

• Find the location of the file:

The problem is that the latitude and longtitude argumets are "attached" directly to the -GPSLatitute* and -GPSLongtitude* parameter names after the = sign. (The - initial character prevents PowerShell from invoking variable expansion - see GitHub issue #14587.)

One way to work around this is to wrap the -GPSLatitude* and -GPSLongtitude* parameters in " quotes; e.g.

See Exiftool FAQ #17

To prevent duplication when adding new items, specific items can be deleted then added back again in the same command. For example, the following command adds the keywords "one" and "two", ensuring that they are not duplicated if they already existed in the keywords of an image:

exiftool -keywords-=one -keywords+=one -keywords-=two -keywords+=two DIR

The NoDups helper function is used to remove duplicates when they already exist in the file. It isn't used to prevent duplicates from being added in the first place.

So your code was really close. All you needed to add were a few basic concepts to get the first argument into a variable which can be done by checking if a variable is defined or not. Then use the SET command to rebuild all the arguments back into another variable. This requires delayed expansion as described in this question.
