Rated 5 out of 5 stars

Tested for the following functionality: add a large image as an attachment to an email. Click the resize button. Click OK (use default settings). Send.

Review: Works quickly and simply.

Improvement: I'd like the single click to auto resize all images with the default settings but this doesn't seem to work.

This review is for a previous version of the add-on (0.13.1). 

If you want to avoid the dialog to be displayed, disable interactive mode through settings dialog or through quick settings menu options.
