The app works fine however the count of optimised pictures is doubled so that you pay charges My example, I had 88/100 pictures optimised befor the process. Then I optimised 6 pictures and suddenly I was 2 images over quota... 88+6 = 94 not 102 !! Be careful while using this app...

Morevoer I have no proof that the optimised 88 pictures in the first run - I have only 40 product pictures on my webesite....

Nice app with some few cool features like reduce image weight, but only 50 images for free and not enough added value for my store.

Quick and easy. Had difficulty with the .png to jpg which wasn't available as an option. Maybe you need to upgrade for that, but I didn't realize it wasn't included.
