2. Host images on a subdomain
Did you ever have a kiddie pool? Do you remember how long it took to fill it up with your one hose? What if you could’ve used your neighbor’s hose at the same time and filled up the pool twice as fast?
Most web browsers allow only two to four “hoses” or connections from a single domain (like TheHobbyBlogger.com) to download content. So if you have a lot of images on your blog, your readers might have to wait for one or more images to load before they can begin reading your content.
By creating a subdomain such as img.yourdomain.com to host your images, you effectively add a second set of hoses to fill your readers web browsers. This allows your blog content to load simultaneously with your images and speed up your page loads.
