I run Daily Observations on WordPress on a hosted server. And by default, presenting large images on smartphones, iPads, laptops and MacBooks with retina displays are a challenge.
To present the images fast and optimum, you must regenerate the pictures based on the required image sizes. When you do not regenerate the photos, the web server has to do that on the fly. And that costs website presentation speed.
If you already have a fast website and used caching software or a CDN, this is unnecessary. But if this is new or abracadabra, then a few sites can help you determine if you need to speed up your website.
The results from these services determine if you need to speed up your WordPress site.
For my image-heavy site, I used two different plugins.
The first one is a plugin by shortpixel. The idea of shortpixel is that when you upload an image, you upload the version that covers the most significant possible presentation size. But this is seldom the most optimal one. WordPress will regenerate the pictures into smaller ones so that the WordPress site presents the most optimal version of the image available.
They have two plugins.
- The first plugin is shortpixel image optimization. This plugin optimizes the images when uploaded into the WordPress media library.
- With results that go up to 25% reduction. Available in three compression ratios. Lossy, Glossy and Lossless.
- Lossy compression is the best option for most users. The images processed with Lossy algorithms are the most minor optimized images you can get. So, if the speed of your site is paramount and you want the best balance between optimization and picture quality, we recommend you continue to use Lossy optimization.
- Glossy compression is the best choice if you still care about Google Insights, but you believe that a slight loss of page speed is an acceptable compromise for top-notch image quality.
- Lossless compressed, optimized images are pixel-by-pixel identical to the originals, but they offer a smaller reduction than either Lossy or Glossy processed files. If you want your pictures to remain untouched, then select this option.
The second shortpixel plugin is shortpixel adaptive images. This plugin regenerates ‘on-the-fly’ the pictures and places them on a shortpixel CDN(Content Delivery Network). That way, even when compressed and regenerated, they are larger than standard text files delivered from servers that are closer to your viewers’ computers than your website server computer is. The original images that you uploaded are on the WordPress website server. But the optimized images are served to your viewer. Super clever.
The third plugin is Autoptimize.
So if you want a fast website and present your beautiful picture stories to the world, using shortpixel with Autoptimize will speed your website so that reading your blog posts and pictures stories is fun.
What is a ‘CDN’?
CDN stands for Content Delivery Network. It is a network of computers that span the globe. The computers are in data centres worldwide and place files requested by computers like the one you are reading locally. When a file or image comes from a server computer near you, it is much quicker than from the other side of the world.
An intelligent algorithm decides where you are on the internet and points you to the fastest server. Because CDN providers have servers all over the internet and close to the internet exchanges where ISP’s (internet service providers) connect their networks, there is always a CDN server nearby to serve you quickly.
Netflix uses a CDN. The movies you see on your television or smartphone are digital files are placed on Netflix in the united states. But if everyone worldwide looks at a Netflix film that comes from the united states, the internet would get slower. That is why Netflix places server computers in the datacenters of internet service providers. When you want to watch a movie, your Netflix app asks for that specific movie from the server computer in your local data centre. If it is not already there, the movie files are placed on the CDN server so the next person that wants to watch it has the movie presented from the server computer at the internet service providers network.
It is also essential to keep your WordPress site updated. WordPress releases new minor and major versions regularly, and it is crucial to keep them up to date. It is also vital to update all the WordPress plugins and theme files as soon as possible because they close programming holes and fixes bugs that could expose your site to hackers.
I check Daily Observations every week and update the site and plugins accordingly. In the past, I had some issues with one of my websites that were hacked. But updating them helped to keep the bugs away.
