Really easy way, actually.
1.) Install JetPack (free)
2.) Go to the JetPack settings and enable “Photon”.
3.) Profit!
Photon is a FREE CDN for images. It hosts all your images automatically on WordPress’ servers with multiple subdomains so they load incredibly fast. Soon as you publish a new product, and someone views the product, the images are copied to the Photon servers and from then on you no longer serve the images yourself, WordPress does for you. And with their automatic use of 3 or 4 subdomains for the images, they load very fast because of no parallel transfer limitations.
When you first enable Photon, your web server might slow to a crawl for 10-15 minutes for 15,000 images to be copied, but after that it’ll be just fine. Expect it, it’s normal for that much data.
The only JetPack options I leave enabled are Photon for this purpose, their stats, and the Publicize feature. You can disable the rest of the ones enabled by default if you wont need them.
Enjoy your free fix and let me know if you have any questions.
