If you are giving the symlink as the last component in the path,
it will probably not work due to File::Find not following symlinks.
If you use images/items, it will work.

As far as I know, this should have been the case in 4.6 as well,
but I don't have that code to check on it anymore.

In any case, if you change this line in code/Widget/imagedir.widget:

    find($wanted, $dir);

to:

    find({ follow => 1, wanted => $wanted}, $dir);

it should list all the files for the directory. I will look at
possibly adding this to the widget options -- I want to create
a UserTag-bound method of adding custom "Advanced" options anyway.
