image optimize

hi
i test pagespeed in nopcommerce 4.00, can you help me, how i must add address extra folder in optimize image?

i add like this, but not work and image optimize rate in gtmetrix is F(0)

~/Themes/Venture/Content/img
~/wwwroot/images/thumbs

You use correct values.
Plugin has a parameter 'Last datetime of picture optimization'.
Set empty this parameter, save it and run task for minify pictures.

hi again, thank you
worked correctly
but image optimize rate in gtmetrix is E (51).
"Optimize the following images to reduce their size by 60.4KiB (5% reduction)."
i added thumbs folder, but gtmetrix Suggests optimize image in thumbs folder.

Send one picture for example.

And one.
1. Change the last date of optimization and enable debuggin on plugin configure page.
2. Run the task.
3. Send me plugin log file.
