Works perfect!
I really like this plugin. Set and forget! Limited options in the free version, but most of the time this is perfect.
5 star because we cannot give more
Awesome plugin, directly goes to my default install list ! Thank you for the great work !
Was 5 star, now broken. Back to 1.2.0
used to work perfectly. I wish I could find older versions, as 1.2.2 no longer automatically converts images when uploaded. never should have updated. so annoying, and now looking for a new solution.
