Cloudimage is an image CDN with over 200 locations worldwide. The idea is that having a server close to where someone accesses your website will increase loading speed and that is of course a ranking factor for Google. Besides this, Cloudimage also automatically compresses and resizes your images according to the device used. A tablet does not need the same size image as a 4K iMac for instance. This is all done automatically for you. Cloudimage offers integrations with different platforms. I'm using it with wordpress so I'll limit my review to that platform.
Cloudimage integration and use
I've been using Cloudimage for over a month now. Wordpress setup is easy enough. Simply download their plugin from the wordpress repository and add the token from your Cloudimage dashboard. The system will automatically offload your images from your wordpress media folder and start optimising your images. For future posts and image uploads, you simply need to continue using wordpress. So it's important to note that Cloudimage does not actually store your images.
Once the system is setup, anyone accessing your site will have your images streamed from these 200+ worldwide locations. You'll also notice that the url for these images will be changed to something containing cloudimg.io. If you're worried about the impact on SEO, it's possible to add a CNAME to your account so that google knows that they are your images.
Cloudimage also offers you the option to add a watermark to your photos for added security and branding. Overall, many settings are customisable but I only made changes to the image compression quality for now.
Since my site is running through an add optimisation service, my overal configuration is quite complex. Hence I've been contacting their support quite a few times over the last weeks. Nikolay is my contact there and he is always very helpful and courteous.
If you're looking for a trustworthy image CDN service for faster and more optimised page loads, I would highly recommend Cloudimage. They also have a nice roadmap with new features and are always updating their customer base with webinars and emails. They are also based in Europe, and I feel more confident in their longevity than some competitors.
