Lately Facebook implied a maximum amount on the pages that their scrapper will get. This might bring blank shared posts on Facebook, if the page is bigger than 40kb and compression (Gzip) is enabled. This plugin corrects that by disabling gzip, only for Facebook requests. !!! Please use the new one: http://extensions.joomla.org/extensions/core-enhancements/performance/site-performance/27725

A tiny content plugin that create a few different sized images on the fly and also update the markup to use the well established and supported HTML5 image tag srcset Which types of images are supported? Only jpg and png Does it also take care of the intro and full image of an article? No. Are there any precautions? YES! Because the plugin creates the images on the fly if a user saves a new article then the first time a visitor visits that page the load time can be very long. An easy work around is that the creator saves the article with some elevated permissions and then visits the page (granted they have permissions) and then re-edit the article to restore the preferred permissions. Also if you already have a live site, it's highly recommended to create the extra images locally (eg use some browser plugin to visit all your pages in your sitemap). Where are those images stored? The extra images are placed in /media/cached-resp-images Installation Install this plugin then enable it and you're set. Nothing to configure! Is there a way to clean the cached images? Sure: just ftp, ssh or use your host control panel and remove the folder named cached-res-images inside the folder media. CAUTION: Performing this action will force the plugin to regenerate all the required image sizes for each image which will effectively increase geometrically the loading time for each page delivered for the first time!!!
