How can I get Taxonomy Images to work with ‘orderby’ argument?

Try this: within $args, leave ‘taxonomy’ where it is and put the remaining three arguments in a ‘term_args’ sub-array.

Based on the documentation, it appears that the filter passes arguments to get_terms() through a ‘term_args’ sub-array. Your $args array is mixing filter arguments and get_terms() arguments at the same level, and it looks like that isn’t supposed to work.

I have not tested this, but it’s worth a shot.

G’luck!
