Great post, but when there are a lot of images consider inserting them as thumbnails rather than the full image as it can cause issues with loading them for some people, particularly those people on slow/limited connections. (You can fix this with a quick edit to your post if you like.)
Otherwise, if you want your post to have larger images than regular thumbs, you can use the "Upload Images" options and post them as "Medium linked thumbnails", which should load quickly enough for most people. Thanks.
