Title: Image Optimization Last modified: October 29, 2017 --- # Image Optimization * Resolved Anonymous User 14978628 * (@anonymized-14978628) * [8 years, 7 months ago](https://wordpress.org/support/topic/image-optimization-13/) * Hi, where can we find more information about the new image optimization feature? Such as what images does it optimize, what type of optimization e.g., lossless/ lossey, where the optimization occurs e.g., on host server or elsewhere, is there a restore function, what is the cost?

Turned out that it was a mistake. All my images got blurry. So I think we can assume that the optimisation is not lossless. * Plugin Support [Hai Zheng⚡](https://wordpress.org/support/users/hailite/) * (@hailite) * [8 years, 7 months ago](https://wordpress.org/support/topic/image-optimization-13/#post-9633276) * Hi [@arrebarre](https://wordpress.org/support/users/arrebarre/), will talk in your post [https://wordpress.org/support/topic/reverse-image-optimisation/](https://wordpress.org/support/topic/reverse-image-optimisation/) * Plugin Support [Hai Zheng⚡](https://wordpress.org/support/users/hailite/) * (@hailite) * [8 years, 7 months ago](https://wordpress.org/support/topic/image-optimization-13/#post-9633279) * We will provide a restore option in this week. * After optimized, the original image `yourname.jpg` from your site is stored as` yourname.bk.jpg`. * [andyt1980](https://wordpress.org/support/users/andyt1980/) * (@andyt1980) * [8 years, 7 months ago](https://wordpress.org/support/topic/image-optimization-13/#post-9633549) * As per the OP, I would also like more information on how the optimization process actually works?. * Plugin Support [LiteSpeed Lisa](https://wordpress.org/support/users/lclarke/) * (@lclarke) * [8 years, 7 months ago](https://wordpress.org/support/topic/image-optimization-13/#post-9634037) * Hi, guys. * Here’s [some documentation on the process](https://www.litespeedtech.com/support/wiki/doku.php/litespeed_wiki:cache:lscwp:image-optimization#how_it_works).

Thanks * Plugin Support [Hai Zheng⚡](https://wordpress.org/support/users/hailite/) * (@hailite) * [8 years, 7 months ago](https://wordpress.org/support/topic/image-optimization-13/#post-9637997) * If you don’t have .bk.jpg that means that jpg can’t be optimized, so the plugin didn’t fetch it, only fetched .webp file for future usage. * [pako69](https://wordpress.org/support/users/pako69/) * (@pako69) * [8 years, 7 months ago](https://wordpress.org/support/topic/image-optimization-13/#post-9638156) * Ok [@hailite](https://wordpress.org/support/users/hailite/) 🙂 * But I’ll wait for a restore option before going live to all my websites. * Question: I supposed that when we click on the button: Send Optimization Request, it only scan/look at the files that have never been processed? Because on a site I have about 3000 images… * Thanks * Plugin Support [Hai Zheng⚡](https://wordpress.org/support/users/hailite/) * (@hailite) * [8 years, 7 months ago](https://wordpress.org/support/topic/image-optimization-13/#post-9638175) * It will only send the images that are never sent before. Each time you click request, it will mark them as sent in your database. However, if you restored your site, the images will be sent again as the previous mark lost. In that case, I would suggest you don’t do it for now. Later we will add a check for that case. * [n4bblucas](https://wordpress.org/support/users/n4bblucas/) * (@n4bblucas) * [8 years, 7 months ago](https://wordpress.org/support/topic/image-optimization-13/#post-9649868) * Hi, * I clicked to send images to be optimized. It sent 100. It has been a couple days and it does not show any that have been pulled. I disabled wp-cron and setup a manual cron job to ping wp-cron every 60sec. Could this be causing an issue with the image optimizer fetching the optimized images? * Now, when I click to send images to be optimized I get this error “Failed to push to LiteSpeed server: too many images in one post” * Any idea how to fix? Greatly looking forward to the automated update 😉 * Thanks! * Plugin Support [Cold Egg](https://wordpress.org/support/users/eric780217/) * (@eric780217) * [8 years, 7 months ago](https://wordpress.org/support/topic/image-optimization-13/#post-9655613) * Hi n4bblucas, * Do you mind to paste your question on a new post? and please provide your site link if possible. If you want to keep your site link privacy, please send a ticket to LiteSpeed. * Best, Eric Viewing 13 replies - 1 through 13 (of 13 total) The topic ‘Image Optimization’ is closed to new replies. * ![](https://ps.w.org/litespeed-cache/assets/icon-256x256.png?rev=2554181) * [LiteSpeed Cache](https://wordpress.org/plugins/litespeed-cache/) * [Frequently Asked Questions](https://wordpress.org/plugins/litespeed-cache/#faq) * [Support Threads](https://wordpress.org/support/plugin/litespeed-cache/) * [Active Topics](https://wordpress.org/support/plugin/litespeed-cache/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/litespeed-cache/unresolved/) * [Reviews](https://wordpress.org/support/plugin/litespeed-cache/reviews/) * 13 replies * 8 participants * Last reply from: [Cold Egg](https://wordpress.org/support/users/eric780217/) * Last activity: [8 years, 7 months ago](https://wordpress.org/support/topic/image-optimization-13/#post-9655613) * Status: resolved
