Optimizing External Image Host Thumbnails

Question

We use imagebam, imagevenue, pixhost etc. to serve our blog posts thumbnails but those are slows down our website and its score by pagespeed, gtmetrix. How to optimize those external image host thumbnails? How to add expire headers into them? How to leverage their browser caching?

Here is our score: https://gtmetrix.com/reports/www.vintagepornbay.com/lH6oi2Cc PageSpeed Score (43%) YSlow Score (51%)

Answer 1

You can't optimise images that you are not serving.

You can use this plugin to bring the images onto your own server.

• https://wordpress.org/plugins/import-external-images/

Then you can Smush to optimise the images.

• https://wordpress.org/plugins/wp-smushit/

Then use this plugin to add expires headers.
