The originals are replaced automatically, but those don’t appear to be hosted on your website, so I don’t know exactly how you update them. A typical CDN will automatically refresh their servers when a new image is detected, but I’m not familiar with hostingpics.net
No hostingpics.net it’s just for show you my wordpress!
Because I don’t understand since I optimized my images , my website is slower !
why?
Sorry about that, I was sick yesterday, and not looking very closely at what you posted…
There is a distinct possibility that you have a plugin generating images on the front-end for every page load. Sliders and related post plugins are a couple of the common culprits. When they generate those images, EWWW IO also has to optimize them as well, so that results in a slow down when they are not properly caching their images to disk.
Did you figure it out? If not, this is the typical testing procedure:
1. Disable all plugins. Yes, all of them, but make notes on any widgets you might have enabled, as you might have to recreate the widget after you re-enable some plugins.
Did the problem go away?
2a. No, then your problem is not plugin-related, re-enable them again…
2b. Yes, re-enable them one by one until you start noticing problems again.
3. post back here with your results
