for image content, where there is nothing to be saved but #HTTP #requests, you should definitely think twice about #base64 encoding to save requests. Yes, you will save a few HTTP requests, you won’t really be saving bytes, and the user might actually think the experience is #slower because they can’t see the image content as it’s being downloaded. Even if you shave off a few milliseconds of wait time, the #perceived #performance is what matters most.
