The browser can only load 6 images simultaneously from img1. so you have some serious blocking going on. With 8 you the Browser can load 48 images simultaneously. The Bandwidth is then the bottleneck rather tan blocking.

Don't do this unless you have a very specific and good reason - it's a very good way to cause self-induced packet loss by oversubscribing the client connection. In some cases having an extra shard can be a good idea but having to many will just download all of the resources in parallel but really slowly. You're better off getting things set up so that the images are downloaded with the visible ones first and then letting the others load after (either by order in the html or by explicitly lazy-loading them).

Will Chan (Chrome Networking) has a good write-up on it here:
