| each visitor brings their own cpu to do this work whereas the server bandwidth is finite |

Surely that will be a smaller image size than the pre-blurred full res photo (while also reducing client-side CPU/OS requirements). | | |

So if any pre-blurred image is meant to peek out around the edges, those edge widths are dynamic. Otherwise, a low-res blurred image plus high-res non-blurred edges might be less bandwidth if overhead is low enough. |
