@johnsmithbisley: I've juste tested with TB 3.0.4 (fr). It behaves as expected. I strongly suggest you to uninstall any version, restart TB, make sure it's uninstalled then reinstall.
For better experience for everybody, i also suggest you to post messages for JPEG Image Resizer on dedicated thread, not this one ;).
Thanks for your report. You can also contact me directly by email: maybe could we together make this addon a better one.
