Hi,
\I think you can try use W3 Total Cache - with me, I think it's better.
And note important: You should regenerate thumbnails for your site. Please install & activate plugin Regenerate Thumbnails - After installed this plugin, go to admin > Tools > Regen. Thumbnails > Click button "Regenerate All Thumbnails" and wait for it until it's done 100%
\Best Regards,
