Losslessly Compressing Specific Thumbnail Sizes

    I’m trying to reduce my site’s load time and server usage. Google Speed Test tells me that my biggest opportunity is to losslessly compress the 190×152 thumbnails that appear on my homepage.

    This makes sense, and know that there are plugins that can do this for all image sizes (e.g., Smush it), but I only want to compress that one specific thumbnail size (190×152) for all of my portfolio images. Because this is a photography portfolio, maintaining image quality is critical, especially for the larger images.

    Does anyone have any suggestions on how I co accomplish this – or perhaps another suggestion to effectively lighten up my site?

    Thanks,

    Your webpagepagetest.org‘s result is here (it is The standard) :

    Use a Content Delivery Network (CDN), Rackspace Cloud Files is cheaper and almost as good as Akamai (backend is of Akamai). NetDNA /MaxCDN is next option. Third is Amazon. You can use a WordPress Plugin to sync the files. For photography blog a CDN is a must. Some CDN Plugins has compressing function (like using Smush.it). But do not use smush.it for photography blog. Compress on Abobe Photoshop / equivalent (Save for Web option) the main photo file before publishing.

    When the thumbnail images will delivered from CDN, Progressive JPG will not be considered. You can see the test result of one of my blog (I have forgotten when I last logged in, the reason is to say that there are lot of thumbnails on homepage) :

    There is a forum on webpagepagetest.org for page speed. You can ask more tips and tricks. At current state you can have a score of 95+ with minimal tweaks.

    The problem is not with wordpress, the problem is with us who upload uncompress files to our servers and then think wordpress or any other plugin should do this for us.

    So better solution is compress all your files first and then upload that files to your server, so whenever your wp script chop off the desired size, it would be automatically compressed.
