Hi Mark, Very peculiar! This suggests that there is something about my environment that makes this work, whereas it otherwise fails. I've been using this as part of a highly customized TW, where the image import is via a custom UI and part of a larger workflow, so it is possible that there is some other part of it that is needed for this to work properly.
However, I did realize that when I was testing yesterday to recreate your problem in a fresh wiki, I made the mistake of using the version of the plugin that I have been working on the last week. Since this is the code base I will be working on going forwards, it would be very helpful to know if this version still gives you the same issue on 5.1.23, before I try to do a deeper dive and identify and resolve the issue. https://saqimtiaz.github.io/sq-tw/temp/import-to-external-file.html Thanks again for the feedback and time invested in testing this.
